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->openmutex, kblockd workqueue completion and partitionscan_work completion.
To avoid the lockdep WARN and the potential deadlock, cut the dependency by running the partitionscanwork not by kblockd workqueue but by nvme_wq.
