Re: [PATCH v3] scsi: core: Fix shost->cmd_per_lun calculation in scsi_add_host_with_dma()

Dexuan,

After commit ea2f0f77538c, a 416-CPU VM running on Hyper-V hangs during boot because the hv_storvsc driver sets scsi_driver.can_queue to an "int" value that exceeds SHRT_MAX, and hence scsi_add_host_with_dma() sets shost->cmd_per_lun to a negative "short" value.

Use min_t(int, ...) to fix the issue.

I queued this up as a short term workaround. However, I am hoping that the rework of the scaling code in storvsc lands soon.
