From: Josef Bacik <josef@xxxxxxxxxxxxxx> [ Upstream commit 592fbcd50c99b8adf999a2a54f9245caff333139 ] We call btrfs_update_root in btrfs_update_reloc_root, which can fail for all sorts of reasons, including IO errors. Instead of panicing the box lets return the error, now that all callers properly handle those errors.
