+Subject: gfs2: initialize transaction tr_ailX_lists earlier
+
+From: Bob Peterson <rpeterso@redhat.com>
+
+commit cbcc89b630447ec7836aa2b9242d9bb1725f5a61 upstream.
+
+Since transactions may be freed shortly after they're created, before
+a log_flush occurs, we need to initialize their ail1 and ail2 lists
+earlier. Before this patch, the ail1 list was initialized in gfs2_log_flush().
+This moves the initialization to the point when the transaction is first
+created.
