Qu Wenruo fec462240d btrfs-progs: mkfs: error out gracefully for --rootdir ... --rootdir option will start a transaction to fill the fs, however if something goes wrong, from ENOSPC to lack of permission, we won't commit the transaction and cause BUG_ON triggered by uncommitted transaction: ------ extent buffer leak: start 29392896 len 16384 extent_io.c:579: free_extent_buffer: BUG_ON `eb->flags & EXTENT_DIRTY` triggered, value 1 ------ The root fix is to introduce btrfs_abort_transaction() in btrfs-progs, however in this particular case, we can workaround it by force committing the transaction. Since during mkfs, the magic of btrfs is set to an invalid one, without setting fs_info->finalize_on_close() the fs is never able to be mounted. So even we force to commit wrong transaction we won't screw up things worse.
