      Merge tag 'for-5.1/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
      
      Pull device mapper updates from Mike Snitzer:
      
       - Update bio-based DM core to always call blk_queue_split() and update
         DM targets to properly advertise discard limits that
         blk_queue_split() looks at when dtermining to split discard. Whereby
         allowing DM core's own 'split_discard_bios' to be removed.
      
       - Improve DM cache target to provide support for discard passdown to
         the origin device.
      
       - Introduce support to directly boot to a DM mapped device from init by
         using dm-mod.create= module param. This eliminates the need for an
         elaborate initramfs that is otherwise needed to create DM devices.
      
         This feature's implementation has been worked on for quite some time
         (got up to v12) and is of particular interest to Android and other
         more embedded platforms (e.g. ARM).
      
       - Rate limit errors from the DM integrity target that were identified
         as the cause for recent NMI hangs due to console limitations.
      
       - Add sanity checks for user input to thin-pool and external snapshot
         creation.
      
       - Remove some unused leftover kmem caches from when old .request_fn
         request-based support was removed.
      
       - Various small cleanups and fixes to targets (e.g. typos, needless
         unlikely() annotations, use struct_size(), remove needless
         .direct_access method from dm-snapshot)
      
      * tag 'for-5.1/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm:
        dm integrity: limit the rate of error messages

       "This is mostly update of the usual drivers: arcmsr, qla2xxx, lpfc,

        Additionally Christoph refactored gdth as part of the dma changes. The
        major mid-layer change this time is the removal of bidi commands and
        with them the whole of the osd/exofs driver and filesystem. This is a

       "First: Ted, Jaegeuk, and I have decided to add me as a co-maintainer
        for fscrypt, and we're now using a shared git tree. So we've updated
        MAINTAINERS accordingly, and I'm doing the pull request this time.
      
        The actual changes for v5.1 are:
      
         - Remove the fs-specific kconfig options like CONFIG_EXT4_ENCRYPTION
           and make fscrypt support for all fscrypt-capable filesystems be
           controlled by CONFIG_FS_ENCRYPTION, similar to how CONFIG_QUOTA
           works.
      
         - Improve error code for rename() and link() into encrypted
           directories.
      
         - Various cleanups"

      Pull io_uring IO interface from Jens Axboe:
       "Second attempt at adding the io_uring interface.
      
        Since the first one, we've added basic unit testing of the three
        system calls, that resides in liburing like the other unit tests that
        we have so far. It'll take a while to get full coverage of it, but
        we're working towards it. I've also added two basic test programs to
        tools/io_uring. One uses the raw interface and has support for all the
        various features that io_uring supports outside of standard IO, like
        fixed files, fixed IO buffers, and polled IO. The other uses the
        liburing API, and is a simplified version of cp(1).
      
        This adds support for a new IO interface, io_uring.
      
        io_uring allows an application to communicate with the kernel through
        two rings, the submission queue (SQ) and completion queue (CQ) ring.
        This allows for very efficient handling of IOs, see the v5 posting for
        some basic numbers:
      
          https://lore.kernel.org/linux-block/20190116175003.17880-1-axboe@kernel.dk/
      
        Outside of just efficiency, the interface is also flexible and
        extendable, and allows for future use cases like the upcoming NVMe
        key-value store API, networked IO, and so on. It also supports async
        buffered IO, something that we've always failed to support in the
        kernel.
      
        Outside of basic IO features, it supports async polled IO as well.
        This particular feature has already been tested at Facebook months ago
        for flash storage boxes, with 25-33% improvements. It makes polled IO
        actually useful for real world use cases, where even basic flash sees
        a nice win in terms of efficiency, latency, and performance. These
        boxes were IOPS bound before, now they are not.
      
        This series adds three new system calls. One for setting up an
        io_uring instance (io_uring_setup(2)), one for submitting/completing
        IO (io_uring_enter(2)), and one for aux functions like registrating
        file sets, buffers, etc (io_uring_register(2)). Through the help of
        Arnd, I've coordinated the syscall numbers so merge on that front
        should be painless.
      
        Jon did a writeup of the interface a while back, which (except for
        minor details that have been tweaked) is still accurate. Find that
        here:
      
          https://lwn.net/Articles/776703/
      
        Huge thanks to Al Viro for helping getting the reference cycle code
        correct, and to Jann Horn for his extensive reviews focused on both
        security and bugs in general.
      
        There's a userspace library that provides basic functionality for
        applications that don't need or want to care about how to fiddle with
        the rings directly. It has helpers to allow applications to easily set
        up an io_uring instance, and submit/complete IO through it without
        knowing about the intricacies of the rings. It also includes man pages
        (thanks to Jeff Moyer), and will continue to grow support helper
        functions and features as time progresses. Find it here:
      
          git://git.kernel.dk/liburing
      
        Fio has full support for the raw interface, both in the form of an IO
        engine (io_uring), but also with a small test application (t/io_uring)
        that can exercise and benchmark the interface"

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.1 cycle:
      
        Core changes:
      
         - The big change this time around is the irqchip handling in the
           qualcomm pin controllers, closely coupled with the gpiochip. This
           rework, in a classic fall-between-the-chairs fashion has been
           sidestepped for too long.
      
           The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms
           have been rewritten to use hierarchical irqchip. This creates the
           base from which I intend to gradually pull support for hierarchical
           irqchips into the gpiolib irqchip helpers to cut down on duplicate
           code.
      
           We have too many hacks in the kernel because people have been
           working around the missing hierarchical irqchip for years, and once
           it was there, noone understood it for a while. We are now slowly
           adapting to using it.
      
           This is why this pull requests include changes to MFD, SPMI,
           IRQchip core and some ARM Device Trees pertaining to the Qualcomm
           chip family. Since Qualcomm have so many chips and such large
           deployments it is paramount that this platform gets this right, and
           now it (hopefully) does.
      
         - Core support for pull-up and pull-down configuration, also from the
           device tree. When a simple GPIO chip supports an "off or on" pull-up
           or pull-down resistor, we provide a way to set this up using
           machine descriptors or device tree.
      
           If more elaborate control of pull up/down (such as resistance shunt
           setting) is required, drivers should be phased over to use pin
           control. We do not yet provide a userspace ABI for this pull
           up-down setting but I suspect the makers are going to ask for it
           soon enough. PCA953x is the first user of this new API.
      
         - The GPIO mockup driver has been revamped after some discussion
           improving the IRQ simulator in the process.
      
           The idea is to make it possible to use the mockup for both testing
           and virtual prototyping, e.g. when you do not yet have a GPIO
           expander to play with but really want to get something to develop
           code around before hardware is available. It's neat. The blackbox
           testing usecase is currently making its way into kernelci.
      
         - ACPI GPIO core preserves non direction flags when updating flags.
      
         - A new device core helper for devm_platform_ioremap_resource() is
           funneled through the GPIO tree with Greg's ACK.
      
        New drivers:
      
         - TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O)
      
         - Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
      
         - AMD G-Series PCH (Platform Controller Hub) GPIO driver.
      
         - Fintek F81804 & F81966 subvariants.
      
         - PCA953x now supports NXP PCAL6416.
      
        Driver improvements:
      
         - IRQ support on the Nintendo Wii (Hollywood) GPIO.
      
         - get_direction() support for the MVEBU driver.
      
         - Set the right output level on SAMA5D2.

      gfs2: Fix missed wakeups in find_insert_glock · 605b0487
      Andreas Gruenbacher authored
      Mark Syms has reported seeing tasks that are stuck waiting in
      find_insert_glock.  It turns out that struct lm_lockname contains four padding
      bytes on 64-bit architectures that function glock_waitqueue doesn't skip when
      hashing the glock name.  As a result, we can end up waking up the wrong
      waitqueue, and the waiting tasks may be stuck forever.
      
      Fix that by using ht_parms.key_len instead of sizeof(struct lm_lockname) for
      the key length.

      gpio: gpio-omap: fix level interrupt idling · d01849f7
      Russell King authored
      Tony notes that the GPIO module does not idle when level interrupts are
      in use, as the wakeup appears to get stuck.
      
      After extensive investigation, it appears that the wakeup will only be
      cleared if the interrupt status register is cleared while the interrupt
      is enabled. However, we are currently clearing it with the interrupt
      disabled for level-based interrupts.
      
      It is acknowledged that this observed behaviour conflicts with a
      statement in the TRM:
      
      CAUTION
        After servicing the interrupt, the status bit in the interrupt status
        register (GPIOi.GPIO_IRQSTATUS_0 or GPIOi.GPIO_IRQSTATUS_1) must be
        reset and the interrupt line released (by setting the corresponding
        bit of the interrupt status register to 1) before enabling an
        interrupt for the GPIO channel in the interrupt-enable register
        (GPIOi.GPIO_IRQSTATUS_SET_0 or GPIOi.GPIO_IRQSTATUS_SET_1) to prevent
        the occurrence of unexpected interrupts when enabling an interrupt
        for the GPIO channel.
      
      However, this does not appear to be a practical problem.
      
      Further, as reported by Grygorii Strashko <grygorii.strashko@ti.com>,
      the TI Android kernel tree has an earlier similar patch as "GPIO: OMAP:
      Fix the sequence to clear the IRQ status" saying:
      
       if the status is cleared after disabling the IRQ then sWAKEUP will not
       be cleared and gates the module transition
      
      When we unmask the level interrupt after the interrupt has been handled,
      enable the interrupt and only then clear the interrupt. If the interrupt
      is still pending, the hardware will re-assert the interrupt status.
      
      Should the caution note in the TRM prove to be a problem, we could
      use a clear-enable-clear sequence instead.

      The commit 0cdf21b3
      
        ("gpio: pca953x: set the PCA_PCAL flag also when matching by DT")
      
      introduces a helper macro which tells that chip supports latched interrupts,
      but the macro was never used for ACPI or legacy enumeration.
      
      So, make use of it for legacy and ACPI enumeration.
