  step_into(): move fetching ->d_inode past handle_mounts() (2022-07-06 13:16:07 -0400)

----------------------------------------------------------------
	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().

Signed-off-by: Al Viro <viro@...iv.linux.org.uk>

----------------------------------------------------------------
Al Viro (10):
      __follow_mount_rcu(): verify that mount_lock remains unchanged
      namei: get rid of pointless unlikely(read_seqcount_retry(...))
      follow_dotdot{,_rcu}(): change calling conventions
      switch try_to_unlazy_next() to __legitimize_mnt()
      namei: move clearing LOOKUP_RCU towards rcu_read_unlock()
      namei: stash the sampled ->d_seq into nameidata
      step_into(): lose inode argument
      follow_dotdot{,_rcu}(): don't bother with inode
      lookup_fast(): don't bother with inode
      step_into(): move fetching ->d_inode past handle_mounts()
