Subject: [PATCH 1/3] io_uring: fix drain with rsrc CQEs
Date: Tue, 27 Apr 2021 16:13:51 +0100	[thread overview]
Message-ID: <2b32f5f0a40d5928c3466d028f936e167f0654be.1619536280.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

Resource emitted CQEs are not bound to requests, so fix up counters used
for DRAIN/defer logic.

Fixes: b60c8dce33895 ("io_uring: preparation for rsrc tagging")
