      Pull oprofile and dcookies removal from Viresh Kumar:
       "Remove oprofile and dcookies support
      
        The 'oprofile' user-space tools don't use the kernel OPROFILE support
        any more, and haven't in a long time. User-space has been converted to
        the perf interfaces.
      
        The dcookies stuff is only used by the oprofile code. Now that
        oprofile's support is getting removed from the kernel, there is no
        need for dcookies as well.
      
        Remove kernel's old oprofile and dcookies support"

      Pull xfs updates from Darrick Wong:
       "There's a lot going on this time, which seems about right for this
        drama-filled year.
      
        Community developers added some code to speed up freezing when
        read-only workloads are still running, refactored the logging code,
        added checks to prevent file extent counter overflow, reduced iolock
        cycling to speed up fsync and gc scans, and started the slow march
        towards supporting filesystem shrinking.
      
        There's a huge refactoring of the internal speculative preallocation
        garbage collection code which fixes a bunch of bugs, makes the gc
        scheduling per-AG and hence multithreaded, and standardizes the retry
        logic when we try to reserve space or quota, can't, and want to
        trigger a gc scan. We also enable multithreaded quotacheck to reduce
        mount times further. This is also preparation for background file gc,
        which may or may not land for 5.13.
      
        We also fixed some deadlocks in the rename code, fixed a quota
        accounting leak when FSSETXATTR fails, restored the behavior that
        write faults to an mmap'd region actually cause a SIGBUS, fixed a bug
        where sgid directory inheritance wasn't quite working properly, and
        fixed a bug where symlinks weren't working properly in ecryptfs. We
        also now advertise the inode btree counters feature that was
        introduced two cycles ago.
      
        Summary:
      
         - Fix an ABBA deadlock when renaming files on overlayfs.
      
         - Make sure that we can't overflow the inode extent counters when
           adding to or removing extents from a file.
      
         - Make directory sgid inheritance work the same way as all the other
           filesystems.
      
         - Don't drain the buffer cache on freeze and ro remount, which should
           reduce the amount of time if read-only workloads are continuing
           during the freeze.
      
         - Fix a bug where symlink size isn't reported to the vfs in ecryptfs.
      
         - Disentangle log cleaning from log covering. This refactoring sets
           us up for future changes to the log, though for now it simply means
           that we can use covering for freezes, and cleaning becomes
           something we only do at unmount.
      
         - Speed up file fsyncs by reducing iolock cycling.
      
         - Fix delalloc blocks leaking when changing the project id fails
           because of input validation errors in FSSETXATTR.
      
         - Fix oversized quota reservation when converting unwritten extents
           during a DAX write.
      
         - Create a transaction allocation helper function to standardize the
           idiom of allocating a transaction, reserving blocks, locking
           inodes, and reserving quota. Replace all the open-coded logic for
           file creation, file ownership changes, and file modifications to
           use them.
      
         - Actually shut down the fs if the incore quota reservations get
           corrupted.
      
         - Fix background block garbage collection scans to not block and to
           actually clean out CoW staging extents properly.
      
         - Run block gc scans when we run low on project quota.
      
         - Use the standardized transaction allocation helpers to make it so
           that ENOSPC and EDQUOT errors during reservation will back out,
           invoke the block gc scanner, and try again. This is preparation for
           introducing background inode garbage collection in the next cycle.
      
         - Combine speculative post-EOF block garbage collection with
           speculative copy on write block garbage collection.
      
         - Enable multithreaded quotacheck.
      
         - Allow sysadmins to tweak the CPU affinities and maximum concurrency
           levels of quotacheck and background blockgc worker pools.
      
         - Expose the inode btree counter feature in the fs geometry ioctl.
      
         - Cleanups of the growfs code in preparation for starting work on
           filesystem shrinking.
      
         - Fix all the bloody gcc warnings that the maintainer knows about. :P
      
         - Fix a RST syntax error.
      
         - Don't trigger bmbt corruption assertions after the fs shuts down.
      
         - Restore behavior of forcing SIGBUS on a shut down filesystem when
           someone triggers a mmap write fault (or really, any buffered
           write)"

      Pull iomap updates from Darrick Wong:
       "The big change in this cycle is some new code to make it possible for
        XFS to try unaligned directio overwrites without taking locks. If the
        block is fully written and within EOF (i.e. doesn't require any
        further fs intervention) then we can let the unlocked write proceed.
        If not, we fall back to synchronizing direct writes.
      
        Summary:
      
         - Adjust the final parameter of iomap_dio_rw.
      
         - Add a new flag to request that iomap directio writes return EAGAIN
           if the write is not a pure overwrite within EOF; this will be used
           to reduce lock contention with unaligned direct writes on XFS.
      
         - Amend XFS' directio code to eliminate exclusive locking for
           unaligned direct writes if the circumstances permit"

       "This contains a somewhat important but rarely reproduced fix reported
        month ago for platforms which have weak memory model (e.g. arm64).
      
        The root cause is that test_bit/set_bit atomic operations are actually
        implemented in relaxed forms, and uninitialized fields governed by an
        atomic bit could be observed in advance due to memory reordering thus
        memory barrier pairs should be used.

      Pull f2fs updates from Jaegeuk Kim:
       "We've added two major features: 1) compression level and 2)
        checkpoint_merge, in this round.
      
        Compression level expands 'compress_algorithm' mount option to accept
        parameter as format of <algorithm>:<level>, by this way, it gives a
        way to allow user to do more specified config on lz4 and zstd
        compression level, then f2fs compression can provide higher compress
        ratio.
      
        checkpoint_merge creates a kernel daemon and makes it to merge
        concurrent checkpoint requests as much as possible to eliminate
        redundant checkpoint issues. Plus, we can eliminate the sluggish issue
        caused by slow checkpoint operation when the checkpoint is done in a
        process context in a cgroup having low i/o budget and cpu shares.
      
        Enhancements:
         - add compress level for lz4 and zstd in mount option
         - checkpoint_merge mount option
         - deprecate f2fs_trace_io
      
        Bug fixes:
         - flush data when enabling checkpoint back
         - handle corner cases of mount options
         - missing ACL update and lock for I_LINKABLE flag
         - attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
         - fix potential deadlock in compression flow
         - fix wrong submit_io condition
      
        As usual, we've cleaned up many code flows and fixed minor bugs"

      Pull btrfs updates from David Sterba:
       "This brings updates of space handling, performance improvements or bug
        fixes. The subpage block size and zoned mode features have reached
        state where they're usable but with limitations.
      
        Performance or related:
      
         - do not block on deleted block group mutex in the cleaner, avoids
           some long stalls
      
         - improved flushing: make it work better with ticket space
           reservations and avoid excessive transaction commits in some
           scenarios, slightly improves throughput for random write load
      
         - preemptive background flushing: separate the logic from ticket
           reservations, improve the accounting and decisions when to flush in
           low space conditions
      
         - less lock contention related to running delayed refs, let just one
           thread do the flushing when there are many inside transaction
           commit
      
         - dbench workload improvements: avoid unnecessary work when logging
           inodes, fewer fallbacks to transaction commit and thus less waiting
           for it (+7% throughput, -20% latency)
      
        Core:
      
         - subpage block size
            - currently read-only support
            - refactor and generalize code where sectorsize is assumed to be
              page size, add the subpage handling everywhere
            - the read-write support is on the way, page sizes are still
              limited to 4K or 64K
      
         - zoned mode, first working version but with limitations
            - SMR/ZBC/ZNS friendly allocation mode, utilizing the "no fixed
              location for structures" and chunked allocation
            - superblock as the only fixed data structure needs special
              handling, uses 2 consecutive zones as a ring buffer
            - tree-log support with a dedicated block group to avoid unordered
              writes
            - emulated zones on non-zoned devices
            - not yet working
            - all non-single block group profiles, requires more zone write
              pointer synchronization between the multiple block groups
            - fitrim due to dependency on space cache, can be implemented
      
        Fixes:
      
         - ref-verify: proper tree owner and node level tracking
      
         - fix pinned byte accounting, causing some early ENOSPC now more
           likely due to other changes in delayed refs
      
        Other:
      
         - error handling fixes and improvements
      
         - more error injection points
      
         - more function documentation
      
         - more and updated tracepoints
      
         - subset of W=1 checked by default
      
         - update comments to allow more automatic kdoc parameter checks"

            * Fix max CPU frequency discovery in the intel_pstate driver and
              make janitorial changes in it (Chen Yu, Rafael Wysocki, Nigel
              Christian).

         - Simplify and clean up devfreq somewhat (Lukasz Luba, Yang Li,
           Pierre Kuo).
      
         - Update the generic power domains (genpd) framework:

           PM-runtime (Bhaskar Chowdhury, Bjorn Helgaas, Rikard Falkeborn,

              future family updates easier (Nathan Fontenot, Robert Richter).

      tty: protect tty_write from odd low-level tty disciplines · 3342ff26
      Linus Torvalds authored
      Al root-caused a new warning from syzbot to the ttyprintk tty driver
      returning a write count larger than the data the tty layer actually gave
      it.  Which confused the tty write code mightily, and with the new
      iov_iter based code, caused a WARNING in iov_iter_revert().
      
      syzbot correctly bisected the source of the new warning to commit
      9bb48c82 ("tty: implement write_iter"), but the oddity goes back
      much further, it just didn't get caught by anything before.
