      Pull scheduler fixes from Thomas Gleixner:
       "A couple of scheduler fixes:
         - Make the conditional update of the overutilized state work
           correctly by caching the relevant flags state before overwriting
           them and checking them afterwards.
         - Fix a data race in the wakeup path which caused loadavg on ARM64
           platforms to become a random number generator.
         - Fix the ordering of the iowaiter accounting operations so it can't
           be decremented before it is incremented.
         - Fix a bug in the deadline scheduler vs. priority inheritance when a
           non-deadline task A has inherited the parameters of a deadline task
           B and then blocks on a non-deadline task C.
           The second inheritance step used the static deadline parameters of
           task A, which are usually 0, instead of further propagating task
           B's parameters. The zero initialized parameters trigger a bug in
           the deadline scheduler"

      afs: Fix speculative status fetch going out of order wrt to modifications · a9e5c87c
      David Howells authored
      When doing a lookup in a directory, the afs filesystem uses a bulk
      status fetch to speculatively retrieve the statuses of up to 48 other
      vnodes found in the same directory and it will then either update extant
      inodes or create new ones - effectively doing 'lookup ahead'.
      To avoid the possibility of deadlocking itself, however, the filesystem
      doesn't lock all of those inodes; rather just the directory inode is
      locked (by the VFS).
      When the operation completes, afs_inode_init_from_status() or
      afs_apply_status() is called, depending on whether the inode already
      exists, to commit the new status.
      A case exists, however, where the speculative status fetch operation may
      straddle a modification operation on one of those vnodes.  What can then
      happen is that the speculative bulk status RPC retrieves the old status,
      and whilst that is happening, the modification happens - which returns
      an updated status, then the modification status is committed, then we
      attempt to commit the speculative status.
      This results in something like the following being seen in dmesg:
      	kAFS: vnode modified {100058:861} 8->9 YFS.InlineBulkStatus
      showing that for vnode 861 on volume 100058, we saw YFS.InlineBulkStatus
      say that the vnode had data version 8 when we'd already recorded version
      9 due to a local modification.  This was causing the cache to be
      invalidated for that vnode when it shouldn't have been.  If it happens
      on a data file, this might lead to local changes being lost.
      Fix this by ignoring speculative status updates if the data version
      doesn't match the expected value.
      Note that it is possible to get a DV regression if a volume gets
      restored from a backup - but we should get a callback break in such a
      case that should trigger a recheck anyway.  It might be worth checking
      the volume creation time in the volsync info and, if a change is
      observed in that (as would happen on a restore), invalidate all caches
      associated with the volume.
