This new attribute is supposed to be used instead of NFTA_DEVICE_NAME
for simple wildcard interface specs. It holds a NUL-terminated string
representing an interface name prefix to match on.

While kernel code to distinguish full names from prefixes in
NFTA_DEVICE_NAME is simpler than this solution, reusing the existing
attribute with different semantics leads to confusion between different
versions of kernel and user space though:

* With old kernels, wildcards submitted by user space are accepted yet
  silently treated as regular names.
* With old user space, wildcards submitted by kernel may cause crashes
  since libnftnl expects NUL-termination when there is none.

Using a distinct attribute type sanitizes these situations as the
receiving part detects and rejects the unexpected attribute nested in
*_HOOK_DEVS attributes.

Pull block fixes from Jens Axboe:
 "A set of fixes for block that should go into this tree. A bit larger
  than what I usually have at this point in time, a lot of that is the
  continued fixing of the lockdep annotation for queue freezing that we
  recently added, which has highlighted a number of little issues here
  and there. This contains:

   - MD pull request via Yu:

       - Add a legacy_async_del_gendisk mode, to prevent a user tools
         regression. New user tools releases will not use such a mode,
         the old release with a new kernel now will have warning about
         deprecated behavior, and we prepare to remove this legacy mode
         after about a year later

       - The rename in kernel causing user tools build failure, revert
         the rename in mdp_superblock_s

       - Fix a regression that interrupted resync can be shown as
         recover from mdstat or sysfs

   - Improve file size detection for loop, particularly for networked
     file systems, by using getattr to get the size rather than the
     cached inode size.

   - Hotplug CPU lock vs queue freeze fix

   - Lockdep fix while updating the number of hardware queues

   - Fix stacking for PI devices

   - Silence bio_check_eod() for the known case of device removal where
     the size is truncated to 0 sectors"

The security-version-number check should be used rather
than the runtime version check for driver updates.

Otherwise, the firmware update would fail when the update binary had
a lower runtime version number than the current one.

commit 907a99c314a5 ("md: rename recovery_cp to resync_offset") replaces
recovery_cp with resync_offset in mdp_superblock_s which is in md_p.h.
md_p.h is used in userspace too. So mdadm building fails because of this.
This patch revert this change.

Pull TTY fix from Greg KH:
 "Here is a single revert of one of the previous patches that went in
  the last tty/serial merge that is breaking userspace on some platforms
  (specifically powerpc, probably a few others.)

  It accidentially changed the ioctl values of some tty ioctls, which
  breaks xorg.

  The revert has been in linux-next all this week with no reported
  issues"

Pull io_uring fixes from Jens Axboe:

 - Allow vectorized payloads for send/send-zc - like sendmsg, but
   without the hassle of a msghdr.

 - Fix for an integer wrap that should go to stable, spotted by syzbot.
   Nothing alarming here, as you need to be root to hit this.
   Nevertheless, it should get fixed.

   FWIW, kudos to the syzbot crew for having much nicer reproducers now,
   and with nicely annotated source code as well. This is particularly
   useful as syzbot uses the raw interface rather than liburing,
   historically it's been difficult to turn a syzbot reproducer into a
   meaningful test case. With the recent changes, not true anymore!
