From 2eb5909dee9bcce9c0befdef48c00f1132d9de2e Mon Sep 17 00:00:00 2001 From: Bob Peterson Date: Mon, 29 Jan 2018 10:00:23 -0700 Subject: GFS2: Don't try to end a non-existent transaction in unlink Before this patch, if function gfs2_unlink failed to get a valid transaction (for example, not enough journal blocks) it would go to label out_end_trans which did gfs2_trans_end. But if the trans_begin failed, there's no transaction to end, and trying to do so results in: kernel BUG at fs/gfs2/trans.c:117! This patch changes the goto so that it does not try to end a non-existent transaction.
