[RFC PATCH v2 00/18] io_uring, struct filename and audit

Changes compared to v1:
	* putname_to_delayed(): new primitive, hopefully solving the
io_openat2() breakage spotted by Jens
	* Linus' suggestion re saner allocation for struct filename
implemented and carved up [##11--15]

It's obviously doing to slip to the next cycle at this point - I'm not
proposing to merge it in the coming window.

Please, review.  Branch in
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git #work.filename-refcnt
individual patches in followups.

Al Viro (17):
  do_faccessat(): import pathname only once
  do_fchmodat(): import pathname only once
  do_fchownat(): import pathname only once
  do_utimes_path(): import pathname only once
  chdir(2): import pathname only once
  chroot(2): import pathname only once
  user_statfs(): import pathname only once
  do_sys_truncate(): import pathname only once
  do_readlinkat(): import pathname only once
  get rid of audit_reusename()
  ntfs: ->d_compare() must not block
  getname_flags() massage, part 1
  getname_flags() massage, part 2
  struct filename: use names_cachep only for getname() and friends
  struct filename: saner handling of long names
  allow incomplete imports of filenames
  struct filename ->refcnt doesn't need to be atomic

Mateusz Guzik (1):
