[PATCH 0/2] io_uring/cancel: futex and waitid cancel results

[agxr <agxr@disroot.org>]

io_futex_cancel() and io_waitid_cancel() return the number of requests
they canceled, where the rest of what io_try_cancel() calls returns 0.
Commit c74193430feb ("io_uring/timeout: don't end a linked timeout with
1") took care of what that did to a linked timeout.

liburing's futex, waitid, io-cancel, sync-cancel, poll-cancel-all,
cancel-race, futex-kill, link-timeout, timeout and poll-cancel tests
pass on both patched kernels. Unchanged liburing tests pass with patch
1 and fail with patch 2, where they check for the 1.

agxr (2):
  io_uring/cancel: count all canceled futex and waitid requests on
    CANCEL_ALL
  io_uring/cancel: complete single futex or waitid cancel with 0
