Subject: [PATCH 21/21] btrfs: add assertions for releasing trans handle reservations
Date: Fri, 29 Sep 2017 15:44:05 -0400 [thread overview]
Message-ID: <1506714245-23072-22-git-send-email-jbacik@fb.com> (raw)
In-Reply-To: <1506714245-23072-1-git-send-email-jbacik@fb.com>
These are useful for debugging problems where we mess with
trans->block_rsv to make sure we're not screwing something up.
