Subject: [PULL v2 08/10] block/nvme: Properly display doorbell stride length in trace event
Date: Tue,  2 Feb 2021 17:28:32 +0100	[thread overview]
Message-ID: <20210202162834.269789-9-kwolf@redhat.com> (raw)
In-Reply-To: <20210202162834.269789-1-kwolf@redhat.com>

From: Philippe Mathieu-Daudé <philmd@redhat.com>

Commit 15b2260bef3 ("block/nvme: Trace controller capabilities")
misunderstood the doorbell stride value from the datasheet, use
the correct one. The 'doorbell_scale' variable used few lines
later is correct.
