Subject: [git pull] vfs.git more namei.c stuff

        Small namei.c patch series, mostly to simplify the rules
for nameidata state.  It's in #work.namei and it's actually from
the previous cycle - didn't post it for review in time...

	Changes visible outside of fs/namei.c: file_open_root()
calling conventions change, some freed bits in LOOKUP_... space.

The following changes since commit 4f0ed93fb92d3528c73c80317509df3f800a222b:

  LOOKUP_MOUNTPOINT: we are cleaning "jumped" flag too late (2021-04-06 20:33:00 -0400)

  namei: make sure nd->depth is always valid (2021-04-07 13:57:17 -0400)

----------------------------------------------------------------
Al Viro (4):
      switch file_open_root() to struct path
      take LOOKUP_{ROOT,ROOT_GRABBED,JUMPED} out of LOOKUP_... space
      teach set_nameidata() to handle setting the root as well
      namei: make sure nd->depth is always valid
