vhost/scsi: use vmalloc for order-10 allocation
As vhost scsi device struct is large, if the device is created on a busy system, kzalloc() might fail, so this patch does a fallback to vzalloc(). As vmalloc() adds overhead on data-path, add __GFP_REPEAT to kzalloc() flags to do this fallback only when really needed. Reviewed-by:Asias He <asias@redhat.com> Reported-by:
