Merge tag 'vfs-7.2-rc1.inode' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs inode updates from Christian Brauner:
 "This extends the lockless ->i_count handling.

  iput() could already decrement any value greater than one locklessly
  but acquiring a reference always required taking inode->i_lock. Now
  acquiring a reference is lockless as long as the count was already at
  least 1, i.e., only the 0->1 and 1->0 transitions take the lock.

  This avoids the lock for the common cases of nfs calling into the
  inode hash and btrfs using igrab(). Cleanup-wise icount_read_once() is
  added to line up with inode_state_read_once() and the open-coded
  ->i_count loads across the tree are converted, and ihold() is
  relocated and tidied up.

  On top of that some stale lock ordering annotations are retired from
  the inode hash code: iunique() no longer takes the hash lock since the
  inode hash became RCU-searchable and s_inode_list_lock is no longer
  taken under the hash lock either"
