Subject: [PATCH 0/2] io_uring: bug fixes
Date: Sat, 7 Aug 2021 17:13:40 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
From: Nadav Amit <[email protected]>
Two small bug fixes. The first fix is for a real issue that encountered
on 5.13, which caused my workload not to work with a submission queue.
Apparently, on 5.14 it is only a performance issue (i.e., not a
functionality issue).
The second fix is for a theoretical issue.
I did not cc stable, as I leave this decision to the maintainer.
