      Merge tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
      
      Pull acl updates from Christian Brauner:
       "Last cycle we introduced support for mounting overlayfs on top of
        idmapped mounts. While looking into additional testing we realized
        that posix acls don't really work correctly with stacking filesystems
        on top of idmapped layers.
      
        We already knew what the fix were but it would require work that is
        more suitable for the merge window so we turned off posix acls for
        v5.19 for overlayfs on top of idmapped layers with Miklos routing my
        patch upstream in 72a8e05d ("Merge tag 'ovl-fixes-5.19-rc7' [..]").
      
        This contains the work to support posix acls for overlayfs on top of
        idmapped layers. Since the posix acl fixes should use the new
        vfs{g,u}id_t work the associated branch has been merged in. (We sent a
        pull request for this earlier.)
      
        We've also pulled in Miklos pull request containing my patch to turn
        of posix acls on top of idmapped layers. This allowed us to avoid
        rebasing the branch which we didn't like because we were already at
        rc7 by then. Merging it in allows this branch to first fix posix acls
        and then to cleanly revert the temporary fix it brought in by commit
        4a47c638 ("ovl: turn of SB_POSIXACL with idmapped layers
        temporarily").
      
        The last patch in this series adds Seth Forshee as a co-maintainer for
        idmapped mounts. Seth has been integral to all of this work and is
        also the main architect behind the filesystem idmapping work which
        ultimately made filesystems such as FUSE and overlayfs available in
        containers. He continues to be active in both development and review.
        I'm very happy he decided to help and he has my full trust. This
        increases the bus factor which is always great for work like this. I'm
        honestly very excited about this because I think in general we don't
        do great in the bringing on new maintainers department"

      Linus Torvalds authored
      Pull fs idmapping updates from Christian Brauner:
       "This introduces the new vfs{g,u}id_t types we agreed on. Similar to
        k{g,u}id_t the new types are just simple wrapper structs around
        regular {g,u}id_t types.
      
        They allow to establish a type safety boundary in the VFS for idmapped
        mounts preventing confusion betwen {g,u}ids mapped into an idmapped
        mount and {g,u}ids mapped into the caller's or the filesystem's
        idmapping.
      
        An initial set of helpers is introduced that allows to operate on
        vfs{g,u}id_t types. We will remove all references to non-type safe
        idmapped mounts helpers in the very near future. The patches do
        already exist.
      
        This converts the core attribute changing codepaths which become
        significantly easier to reason about because of this change.
      
        Just a few highlights here as the patches give detailed overviews of
        what is happening in the commit messages:
      
         - The kernel internal struct iattr contains type safe vfs{g,u}id_t
           values clearly communicating that these values have to take a given
           mount's idmapping into account.
      
         - The ownership values placed in struct iattr to change ownership are
           identical for idmapped and non-idmapped mounts going forward. This
           also allows to simplify stacking filesystems such as overlayfs that
           change attributes In other words, they always represent the values.
      
         - Instead of open coding checks for whether ownership changes have
           been requested and an actual update of the inode is required we now
           have small static inline wrappers that abstract this logic away
           removing a lot of code duplication from individual filesystems that
           all open-coded the same checks"

       - Delay the completion of lockspace creation until one full recovery
         cycle has completed. This allows more error cases to be returned to
         the caller.
      
       - Remove warnings from the locking layer about delayed network replies.
         The recently added midcomms warnings are much more useful.

      Alexander Aring authored
      The unhold_lkb() function decrements the lock's kref, and
      asserts that the ref count was not the final one.  Use the
      kref_put release function (which should not be called) to
      call the assert, rather than doing the assert based on the
      kref_put return value.  Using kill_lkb() as the release
      function doesn't make sense if we only want to assert.

      fs: dlm: add deprecation Kconfig and warnings for timeouts · 81eeb82f
      Alexander Aring authored
      This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option
      that must be enabled to use two timeout-related features
      that we intend to remove in kernel v6.2.  Warnings are
      printed if either is enabled and used.  Neither has ever
      been used as far as we know.
      
      . The DLM_LSFL_TIMEWARN lockspace creation flag will be
        removed, along with the associated configfs entry for
        setting the timeout.  Setting the flag and configfs file
        would cause dlm to track how long locks were waiting
        for reply messages.  After a timeout, a kernel message
        would be logged, and a netlink message would be sent
        to userspace.  Recently, midcomms messages have been
        added that produce much better logging about actual
        problems with messages.  No use has ever been found
        for the netlink messages.
      
      . The userspace libdlm API has allowed the DLM_LKF_TIMEOUT
        flag with a timeout value to be set in lock requests.
        The lock request would be cancelled after the timeout.
