The BUG_ON condition in btrfs_cancel_balance\ndoes not take this race scenario into account.\n\nHowever, the race condition has no other side effects. We can fix that.\n\nReproducing it with panic trace like this:\n\n  kernel BUG at fs/btrfs/volumes.c:4618!\n  RIP: 0010:btrfs_cancel_balance+0x5cf/0x6a0\n  Call Trace:\n   <TASK>\n   ? do_nanosleep+0x60/0x120\n   ? hrtimer_nanosleep+0xb7/0x1a0\n   ? sched_core_clone_cookie+0x70/0x70\n   btrfs_ioctl_balance_ctl+0x55/0x70\n   btrfs_ioctl+0xa46/0xd20\n   __x64_sys_ioctl+0x7d/0xa0\n   do_syscall_64+0x38/0x80\n   entry_SYSCALL_64_after_hwframe+0x63/0xcd\n\n  Race scenario as follows:\n  > mutex_unlock(&fs_info->balance_mutex);\n  > --------------------\n  > .......issue pause and cancel req in another thread\n  > --------------------\n  > ret = __btrfs_balance(fs_info);\n  >\n  > mutex_lock(&fs_info->balance_mutex);\n  > if (ret == -ECANCELED && atomic_read(&fs_info->balance_pause_req)) {\n  >         btrfs_info(fs_info, \"balance: paused\");\n  >         btrfs_exclop_balance(fs_info, BTRFS_EXCLOP_BALANCE_PAUSED);\n  > }",
