[PATCHv9 0/5] Getting rid of get_unused_fd()

[Yann Droneaud]

Hi,

Please find the 9th revision of my patchset to remove
get_unused_fd() macro.

In linux-next, tag next-20141013, they're currently:

- 33 calls to fd_install()
       with one call part of anon_inode_getfd()
- 27 calls to get_unused_fd_flags()
       with one call part of anon_inode_getfd()
       with another part of get_unused_fd() macro
- 13 calls to anon_inode_getfd()
-  8 calls to anon_inode_getfile()
       with one call part of anon_inode_getfd()
-  5 calls to get_unused_fd()

The following patchset replaces the 5 last calls to
get_unused_fd() by calls to get_unused_fd_flags(0)
and remove the macro so that it won't be used in
newer code.

For some detailed background information, please have
a look at my previous patchset's cover letter[1].

Changes from patchset v8[1]
- fanotify: enable close-on-exec on events' fd when requested in
    fanotify_init()
  DROPPED: applied upstream, commit 0b37e097a648.
- reduce the amount of explanation in cover letter

[PATCHv9 1/5] ia64: trivial: replace get_unused_fd() by get_unused_fd_flags(0)

[Yann Droneaud]

This patch replaces calls to get_unused_fd() with equivalent call to
get_unused_fd_flags(0) to preserve current behavor for existing code.

In a further patch, get_unused_fd() will be removed so that new code
start using get_unused_fd_flags(), with the hope O_CLOEXEC could be
used, either by default or choosen by userspace.
