Subject: [PATCH 03/13] gfs2: Revert "introduce qd_bh_get_or_undo"
Date: Tue, 18 Jun 2024 18:05:07 +0200	[thread overview]
Message-ID: <20240618160517.901589-4-agruenba@redhat.com> (raw)
In-Reply-To: <20240618160517.901589-1-agruenba@redhat.com>

The qd_bh_get_or_undo() helper introduced by that commit doesn't improve
the code much, so revert it and clean things up in a more useful way in
the next commit.

This reverts commit 7dbc6ae60dd7089d8ed42892b6a66c138f0aa7a0.
