Nope, looks fine to me. Though I'd probably prefer just doing an
unconditional PF_FROZEN clear.
/*
* Force unfreeze of the bdi threads before stopping it, since otherwise
* it would never exit if it is stuck in the refrigerator.
*/
list_for_each_entry(wb, &bdi->wb_list, list) {
wb->task->flags &= ~PF_FROZEN;
kthread_stop(wb->task);
}
