Pull io_uring fixes from Jens Axboe:

 - Fix for a potential leak of an iovec, if a specific cleanup path is
   used and the rw_cache is full at the time of the call

 - Fix for a regression added in this cycle, where waitid should be
   using prober release/acquire semantics for updating the wait queue
   head

 - Check for the cancelation bit being set for every work item processed
   by io-wq, not just at the start of the loop. Has no real practical
   implications other than to shut up syzbot doing crazy things that
   grossly overload a system, hence slowing down ring exit

 - A few selftest additions, updating the mini_liburing that selftests
   use

* tag 'io_uring-6.19-20260122' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux:
  selftests/io_uring: support NO_SQARRAY in miniliburing
  selftests/io_uring: add io_uring_queue_init_params
  io_uring/io-wq: check IO_WQ_BIT_EXIT inside work run loop
  io_uring/waitid: fix KCSAN warning on io_waitid->head
  io_uring/rw: free potentially allocated iovec on cache put failure

Add support for IORING_SETUP_NO_SQARRAY in miniliburing.

Note that s390 syscall table is still out of sync as it switches to use the
generic table.  But I'd like to minimize the change in this commit.

Add definitions for the missing __aligned_le64 and __aligned_be64 to

for builds where tools/include/ is on the include path ahead of
