#     Merge tag 'io_uring-5.12-2021-03-21' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring followup fixes from Jens Axboe:
#     
#      - The SIGSTOP change from Eric, so we properly ignore that for
#        PF_IO_WORKER threads.
#     
#      - Disallow sending signals to PF_IO_WORKER threads in general, we're
#        not interested in having them funnel back to the io_uring owning
#        task.
#     
#      - Stable fix from Stefan, ensuring we properly break links for short
#        send/sendmsg recv/recvmsg if MSG_WAITALL is set.
#     
#      - Catch and loop when needing to run task_work before a PF_IO_WORKER
#        threads goes to sleep.
#     
#     * tag 'io_uring-5.12-2021-03-21' of git://git.kernel.dk/linux-block:
#       io_uring: call req_set_fail_links() on short send[msg]()/recv[msg]() with MSG_WAITALL
#       io-wq: ensure task is running before processing task_work
#       signal: don't allow STOP on PF_IO_WORKER threads
#       signal: don't allow sending any signals to PF_IO_WORKER threads
