## Overview

In the Linux kernel, the following vulnerability has been resolved:

iomap: allocate s_dio_done_wq for async reads as well

Since commit 222f2c7c6d14 ("iomap: always run error completions in user
context"), read error completions are deferred to s_dio_done_wq.  This
means the workqueue also needs to be allocated for async reads.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
