Subject: [PATCH v4 07/20] nvme: add context annotations for nvme_ns_head::requeue_list
Date: Mon, 13 Jul 2026 17:24:08 +0530 [thread overview]
Message-ID: <20260713115444.465704-8-nilay@linux.ibm.com> (raw)
In-Reply-To: <20260713115444.465704-1-nilay@linux.ibm.com>
nvme_ns_head::requeue_list is protected by
nvme_ns_head::requeue_lock. Annotate requeue_list with
__guarded_by(&requeue_lock) so that Clang's context analysis can
validate accesses to the list.
