## Overview

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

nvme-multipath: fix lockdep WARN due to partition scan work

Blktests test cases nvme/014, 057 and 058 fail occasionally due to a
lockdep WARN. As reported in the Closes tag URL, the WARN indicates that
a deadlock can happen due to the dependency among disk->open_mutex,
kblockd workqueue completion and partition_scan_work completion.

To avoid the lockdep WARN and the potential deadlock, cut the dependency
by running the partition_scan_work not by kblockd workqueue but by
nvme_wq.

## Remediation

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