Subject: [PATCH blktests v3 19/20] nvme: don't assume namespace id
Date: Tue, 26 Mar 2024 14:14:01 +0100	[thread overview]
Message-ID: <20240326131402.5092-20-dwagner@suse.de> (raw)
In-Reply-To: <20240326131402.5092-1-dwagner@suse.de>

The tests assume that the namespace id is always 1. This might not be
correct in future (e.g. running real targets), thus harden the test by
using the uuid to lookup the correct namespace id.

The passthru test already do this, so it makes also sense to update the
other tests as well.
