Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
block: don&#39;t use submit_bio_noacct_nocheck in blk_zone_wplug_bio_work<br />
<br />
Bios queued up in the zone write plug have already gone through all all<br />
preparation in the submit_bio path, including the freeze protection.<br />
<br />
Submitting them through submit_bio_noacct_nocheck duplicates the work<br />
and can can cause deadlocks when freezing a queue with pending bio<br />
write plugs.<br />
<br />
Go straight to ->submit_bio or blk_mq_submit_bio to bypass the<br />
superfluous extra freeze protection and checks.
