From c0109d289de5a48e54a2d070981a629fc241f112 Mon Sep 17 00:00:00 2001 From: Anand Jain Date: Wed, 7 Oct 2015 17:23:23 +0800 Subject: Btrfs: add missing brelse when superblock checksum fails [ Upstream commit b2acdddfad13c38a1e8b927d83c3cf321f63601a ] Looks like oversight, call brelse() when checksum fails. Further down the code, in the non error path, we do call brelse() and so we don't see brelse() in the goto error paths.
