Re: [PATCH 1/1] [virt] virtio-blk: Use ida to allocate disk index

Current index allocation in virtio-blk is based on a monotonically
increasing variable "index". It could cause some confusion about disk
name in the case of hot-plugging disks. And it's impossible to find the
lowest available index by just maintaining a simple index. So it's
changed to use ida to allocate index via referring to the index
allocation in scsi disk.

Hi Mark,

   I don't believe that we do disk probes in parallel, so the spinlock
is unnecessary.  Otherwise, this looks good.

Thanks,
Rusty.
