From 0e78340f3c1fc603e8016c8ac304766bcc65506e Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 22 Oct 2010 15:26:53 -0400 Subject: [PATCH] Btrfs: fix error handling in btrfs_get_sb If we failed to find the root subvol id, or the subvol=, we would deactivate the locked super and close the devices. The problem is at this point we have gotten the SB all setup, which includes setting super_operations, so when we'd deactiveate the super, we'd do a close_ctree() which closes the devices, so we'd end up closing the devices twice. So if you do something like this mount /dev/sda1 /mnt/test1 mount /dev/sda1 /mnt/test2 -o subvol=xxx umount /mnt/test1 it would blow up (if subvol xxx doesn't exist). This patch fixes that problem.
