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 io_uring/cancel.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) base-commit: ecb6817b769fd7d71af2c9f446188649020b2e53 -- 2.56.0
