      md/raid5: Make logic blocking check consistent with logic that blocks · 6e3f50d3
      Logan Gunthorpe authored
      The check in raid5_make_request differs very slightly from the logic
      that causes it to block lower down. This likely does not cause a bug
      as the check is fuzzy anyway (as reshape may move on between the first
      check and the subsequent check). However, make it consistent so it can
      be cleaned up in a subsequent patch.
      
      The condition which causes the schedule is:
      
       !(mddev->reshape_backwards ? logical_sector < conf->reshape_progress :
         logical_sector >= conf->reshape_progress) &&
        (mddev->reshape_backwards ? logical_sector < conf->reshape_safe :
         logical_sector >= conf->reshape_safe)
      
      The condition that causes the early bailout is made to match this.

      md: unlock mddev before reap sync_thread in action_store · 9dfbdafd
      Guoqing Jiang authored
      Since the bug which commit 8b48ec23 ("md: don't unregister sync_thread
      with reconfig_mutex held") fixed is related with action_store path, other
      callers which reap sync_thread didn't need to be changed.
      
      Let's pull md_unregister_thread from md_reap_sync_thread, then fix previous
      bug with belows.
      
      1. unlock mddev before md_reap_sync_thread in action_store.
      2. save reshape_position before unlock, then restore it to ensure position
         not changed accidentally by others.

      md: Explicitly create command-line configured devices · 05ce7fb9
      Chris Webb authored
      Boot-time assembly of arrays with md= command-line arguments breaks when
      CONFIG_BLOCK_LEGACY_AUTOLOAD is unset. md_setup_drive() in md-autodetect.c
      calls blkdev_get_by_dev(), assuming this implicitly creates the block
      device.
      
      Fix this by attempting to md_alloc() the array first. As in the probe path,
      ignore any error as failure is caught by blkdev_get_by_dev() anyway.

      md: Notify sysfs sync_completed in md_reap_sync_thread() · 9973f0fa
      Logan Gunthorpe authored
      The mdadm test 07layouts randomly produces a kernel hung task deadlock.
      The deadlock is caused by the suspend_lo/suspend_hi files being set by
      the mdadm background process during reshape and not being cleared
      because the process hangs. (Leaving aside the issue of the fragility of
      freezing kernel tasks by buggy userspace processes...)
      
      When the background mdadm process hangs it, is waiting (without a
      timeout) on a change to the sync_completed file signalling that the
      reshape has completed. The process is woken up a couple times when
      the reshape finishes but it is woken up before MD_RECOVERY_RUNNING
      is cleared so sync_completed_show() reports 0 instead of "none".
      
      To fix this, notify the sysfs file in md_reap_sync_thread() after
      MD_RECOVERY_RUNNING has been cleared. This wakes up mdadm and causes
      it to continue and write to suspend_lo/suspend_hi to allow IO to
      continue.

      md: Ensure resync is reported after it starts · b368856a
      Logan Gunthorpe authored
      The 07layouts test in mdadm fails on some systems. The failure
      presents itself as the backup file not being removed before the next
      layout is grown into:
      
        mdadm: /dev/md0: cannot create backup file /tmp/md-test-backup:
            File exists
      
      This is because the background mdadm process, which is responsible for
      cleaning up this backup file gets into an infinite loop waiting for
      the reshape to start. mdadm checks the mdstat file if a reshape is
      going and, if it is not, it waits for an event on the file or times
      out in 5 seconds. On faster machines, the reshape may complete before
      the 5 seconds times out, and thus the background mdadm process loops
      waiting for a reshape to start that has already occurred.
      
      mdadm reads the mdstat file to start, but mdstat does not report that the
      reshape has begun, even though it has indeed begun. So the mdstat_wait()
      call (in mdadm) which polls on the mdstat file won't ever return until
      timing out.
      
      The reason mdstat reports the reshape has started is due to an issue
      in status_resync(). recovery_active is subtracted from curr_resync which
      will result in a value of zero for the first chunk of reshaped data, and
      the resulting read will report no reshape in progress.
      
      To fix this, if "resync - recovery_active" is an overloaded value, force
      the value to be MD_RESYNC_ACTIVE so the code reports a resync in progress.

      md: Use enum for overloaded magic numbers used by mddev->curr_resync · eac58d08
      Logan Gunthorpe authored
      Comments in the code document special values used for
      mddev->curr_resync. Make this clearer by using an enum to label these
      values.
      
      The only functional change is a couple places use the wrong comparison
      operator that implied 3 is another special value. They are all
      fixed to imply that 3 or greater is an active resync.

      md/raid5-cache: Drop RCU usage of conf->log · 7769085c
      Logan Gunthorpe authored
      The only place that uses RCU to access conf->log is in
      r5l_log_disk_error(). This function is mostly used in the IO path
      and once with mddev_lock() held in raid5_change_consistency_policy().
      
      It is known that the IO will be suspended before the log is freed and
      r5l_log_exit() is called with the mddev_lock() held.
      
      This should mean that conf->log can not be freed while the function is
      being called, so the RCU protection is not necessary. Drop the
      rcu_read_lock() as well as the synchronize_rcu() and
      rcu_assign_pointer() usage.

      md/raid5: suspend the array for calls to log_exit() · c629f345
      Logan Gunthorpe authored
      The raid5-cache code relies on there being no IO in flight when
      log_exit() is called. There are two places where this is not
      guaranteed so add mddev_suspend() and mddev_resume() calls to these
      sites.
      
      The site in raid5_change_consistency_policy() is in the error path,
      and another similar call site already has suspend/resume calls just
      below it; so it should be equally safe to make that change here.
      
      There is one remaining site in raid5_remove_disk() that we call log_exit()
      without suspending the array. Unfortunately, as the comment stated, we
      cannot call mddev_suspend from raid5d.

      drbd: bm_page_async_io: fix spurious bitmap "IO error" on large volumes · 66757001
      Lars Ellenberg authored
      We usually do all our bitmap IO in units of PAGE_SIZE.
      
      With very small or oddly sized external meta data, or with
      PAGE_SIZE != 4k, it can happen that our last on-disk bitmap page
      is not fully PAGE_SIZE aligned, so we may need to adjust the size
      of the IO.
      
      We used to do that with
        min_t(unsigned int, PAGE_SIZE,
      	last_allowed_sector - current_offset);
      And for just the right diff, (unsigned int)(diff) will result in 0.
      
      A bio of length 0 will correctly be rejected with an IO error
      (and some scary WARN_ON_ONCE()) by the scsi layer.
      
      Do the calculation properly.

      Pull io_uring buffered writes support from Jens Axboe:
       "This contains support for buffered writes, specifically for XFS. btrfs
        is in progress, will be coming in the next release.
      
        io_uring does support buffered writes on any file type, but since the
        buffered write path just always -EAGAIN (or -EOPNOTSUPP) any attempt
        to do so if IOCB_NOWAIT is set, any buffered write will effectively be
        handled by io-wq offload. This isn't very efficient, and we even have
        specific code in io-wq to serialize buffered writes to the same inode
        to avoid further inefficiencies with thread offload.
      
        This is particularly sad since most buffered writes don't block, they
        simply copy data to a page and dirty it. With this pull request, we
        can handle buffered writes a lot more effiently.
      
        If balance_dirty_pages() needs to block, we back off on writes as
        indicated.
      
        This improves buffered write support by 2-3x.
      
        Jan Kara helped with the mm bits for this, and Stefan handled the
        fs/iomap/xfs/io_uring parts of it"

      Pull io_uring updates from Jens Axboe:
      
       - As per (valid) complaint in the last merge window, fs/io_uring.c has
         grown quite large these days. io_uring isn't really tied to fs
         either, as it supports a wide variety of functionality outside of
         that.
      
         Move the code to io_uring/ and split it into files that either
         implement a specific request type, and split some code into helpers
         as well. The code is organized a lot better like this, and io_uring.c
         is now < 4K LOC (me).
      
       - Deprecate the epoll_ctl opcode. It'll still work, just trigger a
         warning once if used. If we don't get any complaints on this, and I
         don't expect any, then we can fully remove it in a future release
         (me).
      
       - Improve the cancel hash locking (Hao)
      
       - kbuf cleanups (Hao)
      
       - Efficiency improvements to the task_work handling (Dylan, Pavel)
      
       - Provided buffer improvements (Dylan)
      
       - Add support for recv/recvmsg multishot support. This is similar to
         the accept (or poll) support for have for multishot, where a single
         SQE can trigger everytime data is received. For applications that
         expect to do more than a few receives on an instantiated socket, this
         greatly improves efficiency (Dylan).
      
       - Efficiency improvements for poll handling (Pavel)
      
       - Poll cancelation improvements (Pavel)

       - Move io_uring types to greatly cleanup the tracing (Pavel)
      
       - Tons of great code cleanups and improvements (Pavel)
      
       - Add a way to do sync cancelations rather than through the sqe -> cqe
         interface, as that's a lot easier to use for some use cases (me).
      
       - Add support to IORING_OP_MSG_RING for sending direct descriptors to a
         different ring. This avoids the usually problematic SCM case, as we
         disallow those. (me)

        Specifics:
      
         - Consolidate the thermal core code by beginning to move the thermal

      Linus Torvalds authored
      Pull ARM boardfile deprecation from Arnd Bergmann:
       "Over the past ten years, new machine support was based on device tree,
        and an initial set of about 400 boards using ATAGS with boardfile for
        booting were grandfathered in, with about half of them either removed
        or converted to DT over time.
      
        Based on the recent mailing list discussion I started, I have now
        turned the findings into a set of patches that marks most board files
        as 'depends on UNUSED_BOARD_FILES', leaving only 38 of the 196 boards.
      
        For the boards that are marked as unused, there are two final chances
        for potential users: The removal is scheduled to take place after the
        longterm stable kernel at the end of 2022, so users can stay on that
        version for another few years, and if anyone still has one of these
        machines and is planning to keep updating kernels beyond that version,
        they can speak up now to have their boards taken off the list again.
      
        Waiting for the LTS release also makes sure that there will be at
        least one longterm kernel that contains the recent multiplatform
        conversion along while still supporting all legacy boards.
      
        The short summary of the current status is:
      
         - The s3c24xx, cns3xxx, iop32x and mv78xx0 platforms have no known
           users and will be removed entirely.
      
         - The mmp and davinci platforms have DT support for the important
           machines and will become DT-only after this.
      
         - s3c64xx, dove, orion5x, and pxa keep some board files to allow
           those to be migrated over to DT more easily, but most board files
           are getting removed now. DT support on these platforms is partially
           working but requires changes to additional drivers for the other
           boards.
      
         - omap1, ep93xx, sa1100, footbridge and rpc have no DT support at the
           moment but have some boards with known users. Removing the board
           files that nobody uses should make it easier to try a DT conversion
           if anyone cares.
      
        There is no explicit timeline what happens with the boards that remain
        after this removal, but I expect to revisit this in the future, and
        with most boards gone, there will be a good time to do a treewide
        review of platform drivers that never gained DT support and have no
        remaining in-tree board files"

       "This branch includes the usual updates to defconfig files, enabling
        additional driver support for the supported platforms.
      
        There is also a global refresh for all of them that reorders the lines
        according to the 'savedefconfig' output, but without removing lines
        that are no longer part of the refresh.
      
        I went through the most common removed lines to also address them
        while making sure to catch renamed options and add them back under the
        new name.
      
        The boardfile deprecation branch is based on top of this to avoid
        conflicts against removing the unused boardfile configs from the
        generic defconfig files"

      Pull ARM DT updates from Arnd Bergmann:
       "As usual, the bulk of the changes for the SoC tree are devicetree file
        updates, and most of these changes are for 64-bit embedded machines.
        As before, there are a ton of style cleanups, and additional hardware
        support for existing machines.
      
        Looking only at the new SoC, the notable additions are:
      
         - A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
           BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
           BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813. Each SoC comes
           with a corresponding reference board.
      
         - The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
           i.MX8 embedded SoCs, now using Cortex-A55 cores and the Ethos-U65
           NPU.
      
         - Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end of
           Arm based Laptop SoCs, and its automotive cousin, the SA8540P. The
           SC8280XP is used in the Lenovo Thinkpad X13s laptop that also gets
           added here in addition to the reference boards.
      
         - Allwinner H616, a newer version of the H6 SoC, targeted at
           Set-top-box applications. It comes with dts files for the Orange Pi
           zero2 single-board computer and the X96 Mate set-top-box
      
         - Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip in the
           Armada SoC family based on the Cortex-A55 core.
      
        New machines based on previously supported SoCs include:
      
         - Several new machines on NXP i.MX platforms: multiple Toradex
           Colibri boards using the "Iris" and "Ixora" carriers, DH
           electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems TQMa8MPQL, and
           phytech phyBOARD-Polis-i.MX8MM.
      
         - Google Chameleon v3 FPGA board based on Intel Arria10 and Stratix
           10 Software Virtual platform, both in the SoCFPGA platform.
      
         - Two new wireless devices based on Broadcom SoCs: The Asus GT-AX6000
           Router and the Cisco Meraki MR26 access point
      
         - Improved Chromebook support for both the Mediatek and Qualcomm SoC
           families brought added machines: Acer Chromebook 514 (MT8192), Acer
           Chromebook Spin 513 (MT8195) and a couple of SC7180 based machines
           including the Lenovo IdeaPad Chromebook Duet 3.
      
         - Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
           Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
      
         - Finally, there are a few development board on other chips: PCB8309
           (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308) DH DRC
           Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm SDM660)"

           efficiency for most workloads, and also increases the reliability
           of energy-efficiency scheduling.
      
         - Optimize/tweak select_idle_cpu() to spend (much) less time
           searching for an idle CPU on overloaded systems. There's reports of
           several milliseconds spent there on large systems with large
           workloads ...
      
           [ Since the search logic changed, there might be behavioral side
             effects. ]
      
         - Improve NUMA imbalance behavior. On certain systems with spare
           capacity, initial placement of tasks is non-deterministic, and such
           an artificial placement imbalance can persist for a long time,
           hurting (and sometimes helping) performance.
      
           The fix is to make fork-time task placement consistent with runtime
           NUMA balancing placement.
      
           Note that some performance regressions were reported against this,
           caused by workloads that are not memory bandwith limited, which
           benefit from the artificial locality of the placement bug(s). Mel
           Gorman's conclusion, with which we concur, was that consistency is
           better than random workload benefits from non-deterministic bugs:
      
              "Given there is no crystal ball and it's a tradeoff, I think
               it's better to be consistent and use similar logic at both fork
               time and runtime even if it doesn't have universal benefit."
      
         - Improve core scheduling by fixing a bug in
           sched_core_update_cookie() that caused unnecessary forced idling.
      
         - Improve wakeup-balancing by allowing same-LLC wakeup of idle CPUs
           for newly woken tasks.
      
         - Fix a newidle balancing bug that introduced unnecessary wakeup
           latencies.
      
        ABI improvements/fixes:
      
         - Do not check capabilities and do not issue capability check denial
           messages when a scheduler syscall doesn't require privileges. (Such
           as increasing niceness.)
      
         - Add forced-idle accounting to cgroups too.
      
         - Fix/improve the RSEQ ABI to not just silently accept unknown flags.
           (No existing tooling is known to have learned to rely on the
           previous behavior.)
      
         - Depreciate the (unused) RSEQ_CS_FLAG_NO_RESTART_ON_* flags.
      
        Optimizations:
      
         - Optimize & simplify leaf_cfs_rq_list()
      
         - Micro-optimize set_nr_{and_not,if}_polling() via try_cmpxchg().
      
        Misc fixes & cleanups:
      
         - Fix the RSEQ self-tests on RISC-V and Glibc 2.35 systems.
      
         - Fix a full-NOHZ bug that can in some cases result in the tick not
           being re-enabled when the last SCHED_RT task is gone from a
           runqueue but there's still SCHED_OTHER tasks around.
      
         - Various PREEMPT_RT related fixes.
      
         - Misc cleanups & smaller fixes"
