      posix_acl: de-union a_refcount and a_rcu · 6d4e56ce
      Jeff Layton authored
      Currently the two are unioned together, but I don't think that's safe.
      It looks like get_cached_acl could race with the last put in
      posix_acl_release. get_cached_acl calls atomic_inc_not_zero on
      a_refcount, but that field could have already been clobbered by
      call_rcu, and may no longer be zero. Fix this by de-unioning the two

      tmpfs: fix regression hang in fallocate undo · 7f556567
      Hugh Dickins authored
      The well-spotted fallocate undo fix is good in most cases, but not when
      fallocate failed on the very first page.  index 0 then passes lend -1
      to shmem_undo_range(), and that has two bad effects: (a) that it will
      undo every fallocation throughout the file, unrestricted by the current
      range; but more importantly (b) it can cause the undo to hang, because
      lend -1 is treated as truncation, which makes it keep on retrying until
      every page has gone, but those already fully instantiated will never go
      away.  Big thank you to xfstests generic/269 which demonstrates this.
      Fixes: b9b4bb26 ("tmpfs: don't undo fallocate past its last page")
