Subject: [PATCH 0/2] LAZY_WAKE misuse fixes
Date: Tue, 30 Apr 2024 16:42:29 +0100	[thread overview]
Message-ID: <[email protected]> (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
