Description
In the Linux kernel, the following vulnerability has been resolved:
block: mark GFP_NOIO around sysfs ->store()
sysfs ->store is called with queue freezed, meantime we have several
->store() callbacks(update_nr_requests, wbt, scheduler) to allocate
memory with GFP_KERNEL which may run into direct reclaim code path,
then potential deadlock can be caused.
Fix the issue by marking NOIO around sysfs ->store()
