Hi Linus,
Was planning on holding these for -rc5, but I think we may as well
flush them out. In this pull request:
- 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.
Please pull!
