Description

Code inspection shows that there may be a missing
lock_dev()/unlock_dev() in around the last
build_and_log_event call in cmd/devfsadm/devfsadm.c:event_handler().
> I believe there should be a lock, since we are accessing the devlink_cache
> and that is initialized by this code.

It looks like this could cause lookup_disk_dev_name
failures, and DEV_NAME_LOOKUP_FAILED "failed to lookup dev name for"
messages from devfsadm.
