I verified the mlx5 and vdpa sim net with rebased tree. No kernel code trace seen.
The last commit in the tree that I verified is below.

virtio_blk: allow 0 as num_request_queues
The default value is 0 meaning "no limit". However if 0
is specified on the command line it is instead silently
converted to 1. Further, the value is already validated
at point of use, there's no point in duplicating code
validating the value when it is set.
Simplify the code while making the behaviour more consistent
by using plain module_param.
