Subject: [PATCH 3/7] btrfs: handle delayed ref head accounting cleanup in abort
Date: Wed, 21 Nov 2018 14:05:41 -0500	[thread overview]
Message-ID: <20181121190545.24798-4-josef@toxicpanda.com> (raw)
In-Reply-To: <20181121190545.24798-1-josef@toxicpanda.com>

We weren't doing any of the accounting cleanup when we aborted
transactions.  Fix this by making cleanup_ref_head_accounting global and
calling it from the abort code, this fixes the issue where our
accounting was all wrong after the fs aborts.
