From 0176260fc30842e358cf34afa7dcd9413db44822 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 10 Jan 2009 06:09:52 -0800 Subject: [PATCH] btrfs: fix for write_super_lockfs/unlockfs error handling Commit c4be0c1dc4cdc37b175579be1460f15ac6495e9a added the ability for write_super_lockfs to return errors, and renamed them to match. But btrfs didn't get converted. Do the minimal conversion to make it compile again.
