Subject: [PATCH 1/2] io_uring/fdinfo: get rid of unnecessary is_cqe32 variable
Date: Sun, 11 Sep 2022 12:18:00 -0600 [thread overview]
Message-ID: <20220911181801.22659-2-axboe@kernel.dk> (raw)
In-Reply-To: <20220911181801.22659-1-axboe@kernel.dk>
We already have the cq_shift, just use that to tell if we have doubly
sized CQEs or not.
While in there, cleanup the CQE32 vs normal CQE size printing.
