      scsi: handle zone resources errors · d8f53b0a
      Damien Le Moal authored
      ZBC or ZAC disks that have a limit on the number of open zones may fail
      a zone open command or a write to a zone that is not already implicitly
      or explicitly open if the total number of open zones is already at the
      maximum allowed.
      
      For these operations, instead of returning the generic BLK_STS_IOERR,
      return BLK_STS_ZONE_OPEN_RESOURCE which is returned as -ETOOMANYREFS to
      the I/O issuer, allowing the device user to act appropriately on these
      relatively benign zone resource errors.

      block: add zone specific block statuses · 3b481d91
      Keith Busch authored
      A zoned device with limited resources to open or activate zones may
      return an error when the host exceeds those limits. The same command may
      be successful if retried later, but the host needs to wait for specific
      zone states before it should expect a retry to succeed. Have the block
      layer provide an appropriate status for these conditions so applications
      can distinuguish this error for special handling.

      block/rnbd-clt: do not cap max_hw_sectors & max_segments with remote device · 050b654b
      Jack Wang authored
      The max_hw_secotrs is only limited by the transport, not remote device,
      block layer on server side will split to the device limit if it's too
      big.
      
      The max_segments, similar, and rtrs server will submit single buffer, so
      no need to cap.

      Pull GPIO updates from Linus Walleij:
       "This time very little driver changes but lots of core changes.
      
        We have some interesting cooperative work for ARM and Intel alike,
        making the GPIO subsystem more and more suitable for industrial
        systems and the like, in addition to the in-kernel users.
      
        We touch driver core (device properties) and lib/* by adding one
        simple string array free function, these are authored by Andy
        Shevchenko who is a well known and recognized core helpers maintainers
        so this should be fine.
      
        We also see some Android GKI-related modularization in the MXC
        drivers.
      
        Core changes:
      
         - The big core change is the updated (v2) userspace character device
           API.
      
           This corrects badly designed 64-bit alignment around the line
           events. We also add the debounce request feature. This echoes the
           often quotes passage from Frederick Brooks "The mythical man-month"
           to always throw one away, which we have seen before in things such
           as V4L2. So we put in a new one and deprecate and obsolete the old
           one.
      
         - All example tools in tools/gpio/* are migrated to the new API to
           set a good example. The libgpiod userspace library has been
           augmented to use this new API pretty much from day 1.
      
         - Some misc API hardening by using strn* function calls has been
           added as well.
      
         - Use the simpler IDA interface for GPIO chip instance enumeration.
      
         - Add device core function for counting string arrays in device
           properties.
      
         - Provide a generic library function kfree_strarray() that can be
           used throughout the kernel.
      
        Driver enhancements:
      
         - The DesignWare dwapb-gpio driver has been enhanced and now uses the
           IRQ handling in the gpiolib core.
      
         - The mockup and aggregator drivers have seen some substantial code
           clean-up and now use more of the core kernel inftrastructure.
      
         - Misc cleanups using dev_err_probe().
      
         - The MXC drivers (Freescale/NXP) can now be built modularized, which
           makes modularized GKI Android kernels happy"

      Pull btrfs updates from David Sterba:
       "Mostly core updates with a few user visible bits and fixes.
      
        Hilights:
      
         - fsync performance improvements
            - less contention of log mutex (throughput +4%, latency -14%,
              dbench with 32 clients)
            - skip unnecessary commits for link and rename (throughput +6%,
              latency -30%, rename latency -75%, dbench with 16 clients)
            - make fast fsync wait only for writeback (throughput +10..40%,
              runtime -1..-20%, dbench with 1 to 64 clients on various
              file/block sizes)
      
         - direct io is now implemented using the iomap infrastructure, that's
           the main part, we still have a workaround that requires an iomap
           API update, coming in 5.10
      
         - new sysfs exports:
            - information about the exclusive filesystem operation status
              (balance, device add/remove/replace, ...)
            - supported send stream version
      
        Core:
      
         - use ticket space reservations for data, fair policy using the same
           infrastructure as metadata
      
         - preparatory work to switch locking from our custom tree locks to
           standard rwsem, now the locking context is propagated to all
           callers, actual switch is expected to happen in the next dev cycle
      
         - seed device structures are now using list API
      
         - extent tracepoints print proper tree id
      
         - unified range checks for extent buffer helpers
      
         - send: avoid using temporary buffer for copying data
      
         - remove unnecessary RCU protection from space infos
      
         - remove unused readpage callback for metadata, enabling several
           cleanups
      
         - replace indirect function calls for end io hooks and remove
           extent_io_ops completely
      
        Fixes:
      
         - more lockdep warning fixes
      
         - fix qgroup reservation for delayed inode and an occasional
           reservation leak for preallocated files
      
         - fix device replace of a seed device
      
         - fix metadata reservation for fallocate that leads to transaction
           aborts
      
         - reschedule if necessary when logging directory items or when
           cloning lots of extents
      
         - tree-checker: fix false alert caused by legacy btrfs root item
      
         - send: fix rename/link conflicts for orphanized inodes
      
         - properly initialize device stats for seed devices
      
         - skip devices without magic signature when mounting
      
        Other:
      
         - error handling improvements, BUG_ONs replaced by proper handling,
           fuzz fixes
      
         - various function parameter cleanups
      
         - various W=1 cleanups
      
         - error/info messages improved
      
        Mishaps:
      
         - commit 62cf5391 ("btrfs: move btrfs_rm_dev_replace_free_srcdev
           outside of all locks") is a rebase leftover after the patch got
           merged to 5.9-rc8 as a466c85e ("btrfs: move
           btrfs_rm_dev_replace_free_srcdev outside of all locks"), the

      Clang-11 shipped support for outputs to asm goto statments along the
      fallthrough path.  Double up some of the get_user() and related macros
      to be able to take advantage of this extended GNU C extension. This
      should help improve the generated code's performance for these accesses.

      x86: Make __put_user() generate an out-of-line call · d55564cf
      Linus Torvalds authored
      Instead of inlining the stac/mov/clac sequence (which also requires
      individual exception table entries and several asm instruction
      alternatives entries), just generate "call __put_user_nocheck_X" for the
      __put_user() cases, the same way we changed __get_user earlier.
      
      Unlike the get_user() case, we didn't have the same nice infrastructure
      to just generate the call with a single case, so this actually has to
      change some of the infrastructure in order to do this.  But that only
      cleans up the code further.
      
      So now, instead of using a case statement for the sizes, we just do the
      same thing we've done on the get_user() side for a long time: use the
      size as an immediate constant to the asm, and generate the asm that way
      directly.
      
      In order to handle the special case of 64-bit data on a 32-bit kernel, I
      needed to change the calling convention slightly: the data is passed in
      %eax[:%edx], the pointer in %ecx, and the return value is also returned
      in %ecx.  It used to be returned in %eax, but because of how %eax can
      now be a double register input, we don't want mix that with a
      single-register output.
      
      The actual low-level asm is easier to handle: we'll just share the code
      between the checking and non-checking case, with the non-checking case
      jumping into the middle of the function.  That may sound a bit too
      special, but this code is all very very special anyway, so...

      x86: Make __get_user() generate an out-of-line call · ea6f043f
      Linus Torvalds authored
      Instead of inlining the whole stac/lfence/mov/clac sequence (which also
      requires individual exception table entries and several asm instruction
      alternatives entries), just generate "call __get_user_nocheck_X" for the
      __get_user() cases.
      
      We can use all the same infrastructure that we already do for the
      regular "get_user()", and the end result is simpler source code, and
      much simpler code generation.
      
      It also means that when I introduce asm goto with input for
      "unsafe_get_user()", there are no nasty interactions with the
      __get_user() code.
