Message-ID: <cover.1714488419.git.asml.silence@gmail.com> (raw)
LAZY_WAKE can't be used with requests for which users expect >1 CQE,
otherwise wait(nr=2) may get stuck waiting for a tw that will never
arrive. Fix up invalid use of LAZY_WAKE with sendzc.
Pavel Begunkov (2):
io_uring/net: fix sendzc lazy wake polling
io_uring/notif: disable LAZY_WAKE for linked notifs
