Hi Linus,
Andres reported a regression with the fix that was merged earlier this
week, where his setup of using signals to interrupt io_uring CQ waits no
longer worked correctly. Fix this, and also limit our use of TWA_SIGNAL
to the case where we need it, and continue using TWA_RESUME for
task_work as before.
Since the original is marked for 5.7 stable, let's flush this one out
before -rc4 is tagged.
Please pull!
