Bug Description

Microsoft would like to request inclusion of the following patch in the 5.4 and later kernels:

a81a38cc6dda ("scsi: storvsc: Parameterize number hardware queues")

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/scsi/storvsc_drv.c?id=a81a38cc6ddaf128c7ca9e3fffff21c243f33c97

This patch adds the ability to set the number of hardware queues with new module parameter, storvsc_max_hw_queues.

This functionality is useful in Microsoft Azure) where decreasing the number of hardware queues has been shown to improve performance.
