Subject: [PATCH v2 2/4] blkparse: Allow request tracking on non md/dm devices
From: Andreas Gruenbacher <agruenba () redhat ! com>
Date: 2020-04-13 19:01:50
Message-ID: 20200413190153.86357-3-agruenba () redhat ! com
[Download RAW message or body]
Fix queue to completion tracking on devices other than md/dm: without this fix,
enabling tracking with the -t option on a non-md/dm device leads to "complete
not found" errors.
