Merge tag 'pull-work.namei' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull vfs namei updates from Al Viro:
 "RCU pathwalk cleanups.

  Storing sampled ->d_seq of the next dentry in nameidata simplifies
  life considerably, especially if we delay fetching ->d_inode until
  step_into()"

* tag 'pull-work.namei' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  step_into(): move fetching ->d_inode past handle_mounts()
  lookup_fast(): don't bother with inode
  follow_dotdot{,_rcu}(): don't bother with inode
  step_into(): lose inode argument
  namei: stash the sampled ->d_seq into nameidata
  namei: move clearing LOOKUP_RCU towards rcu_read_unlock()
  switch try_to_unlazy_next() to __legitimize_mnt()
  follow_dotdot{,_rcu}(): change calling conventions
  namei: get rid of pointless unlikely(read_seqcount_retry(...))
  __follow_mount_rcu(): verify that mount_lock remains unchanged
