Mounting a bad filesystem caused a BUG_ON(). The following is steps to reproduce it. # mkfs.btrfs /dev/sda2 # mount /dev/sda2 /mnt # mkfs.btrfs /dev/sda1 /dev/sda2 (the program says that /dev/sda2 was mounted, and then exits. ) # umount /mnt # mount /dev/sda1 /mnt At the third step, mkfs.btrfs exited in the way of make filesystem. So the initialization of the filesystem didn't finish. So the filesystem was bad, and it caused BUG_ON() when mounting it. But BUG_ON() should be called by the wrong code, not user's operation, so I think it is a bug of btrfs. This patch fixes it.
