From 3a01aa7a25274308fe813a6237f678aed901cea3 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Wed, 6 Mar 2013 01:57:55 -0700 Subject: Btrfs: fix a mismerge in btrfs_balance() Raid56 merge (merge commit e942f88) had mistakenly removed a call to __cancel_balance(), which resulted in balance not cleaning up after itself after a successful finish. (Cleanup includes switching the state, removing the balance item and releasing mut_ex_op testnset lock.) Bring it back.
