From 79525b51acc1c8e331ab47eb131a99f5370a76c2 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Fri, 19 Sep 2025 12:38:58 -0700 Subject: io_uring: fix nvme's 32b cqes on mixed cq The nvme uring_cmd only uses 32b CQEs. If the ring uses a mixed CQ, then we need to make sure we flag the completion as a 32b CQE. On the other hand, if nvme uring_cmd was using a dedicated 32b CQE, the posting was missing the extra memcpy because it only applied to bit CQEs on a mixed CQ.
