From 508794eb5ec2a2b832742e78c6766844b10c0c94 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Sat, 2 Jul 2011 21:24:41 +0000 Subject: [PATCH] Btrfs: don't panic if we get an error while balancing V2 A user reported an error where if we try to balance an fs after a device has been removed it will blow up. This is because we get an EIO back and this is where BUG_ON(ret) bites us in the ass. To fix we just exit.
