Pull close_range() cleanup from Christian Brauner:
 "This is a cleanup for close_range() which was sent as part of a bugfix
  we did some time ago in commit 9b5b872215fe ("file: fix close_range()
  for unshare+cloexec").

  We used to share more code between some helpers for close_range()
  which made retrieving the maximum number of open fds before calling
  into the helpers sensible. But with the introduction of
  CLOSE_RANGE_CLOEXEC and the need to retrieve the number of maximum fds
  once more for CLOSE_RANGE_CLOEXEC that stopped making sense. So the
  code was in a dumb in-limbo state.

  Fix this by simplifying the code a bit.

  The original idea was to only fix the bug itself and make backporting
  easy. And since the cleanup wasn't very pressing I left it in
  linux-next for a very long time. I didn't pull the patches from the
  list again back then which is why they don't have lore-links. So I'm
  listing them below explicitly"
