[PATCHES] fdtable series v3

[Al Viro <viro@zeniv.linux.org.uk>]

Changes since v2:
	Rebased to 6.12-rc2, now that close_range() fix got into
mainline.  No more than that so far (there will be followup
cleanups, but for now I just want it posted and in -next).

Changes since v1:
 	close_range() fix added in the beginning of the series,
dup_fd() calling convention change folded into it (as requested
by Linus), the rest rebased on top of that.
 	sane_fdtable_size() change is dropped, as it's obsoleted
by close_range() fix.  Several patches added at the end of
series.

	Same branch -
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git #work.fdtable
individual patches in followups.

Christian, I can move that to vfs/vfs.git if that's more convenient
for you - we are about to step on each other's toes with that and
your ->f_count work.

Shortlog:

Al Viro (8):
      get rid of ...lookup...fdget_rcu() family
      remove pointless includes of <linux/fdtable.h>
      close_files(): don't bother with xchg()
      move close_range(2) into fs/file.c, fold __close_range() into it
      alloc_fdtable(): change calling conventions.
      file.c: merge __{set,clear}_close_on_exec()
      make __set_open_fd() set cloexec state as well
      expand_files(): simplify calling conventions

Yu Ma (3):
      fs/file.c: remove sanity_check and add likely/unlikely in alloc_fd()
      fs/file.c: conditionally clear full_fds
      fs/file.c: add fast path in find_next_fd()
