Subject: [PATCH 2/5] block/nvme: Display CQ/SQ pointer in nvme_free_queue_pair()
Date: Wed, 6 Oct 2021 18:49:28 +0200 [thread overview]
Message-ID: <20211006164931.172349-3-philmd@redhat.com> (raw)
In-Reply-To: <20211006164931.172349-1-philmd@redhat.com>
For debugging purpose it is helpful to know the CQ/SQ pointers.
We already have a trace event in nvme_free_queue_pair(), extend
it to report these pointer addresses.
