Title
btrfs: fix BUG_ON condition in btrfs_cancel_balance
Summary
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix BUG_ON condition in btrfs_cancel_balance Pausing and canceling balance can race to interrupt balance lead to BUG_ON panic in btrfs_cancel_balance. The BUG_ON condition in btrfs_cancel_balance does not take this race scenario into account. However, the race condition has no other side effects. We can fix that. Reproducing it with panic trace like this: kernel BUG at fs/btrfs/volumes.c:4618!
