Subject: [PATCH v3 0/4] virtio short improvements

Hi,

This series contains small improvements for virtio pci driver.
The main idea is to support surprise removal of virtio pci device when the
driver is already loaded. Future patches will further improve other areas of
hotplug.

Patches 1 to 3 prepare the code to handle surprise removal by marking the
device as broken in patch-4.

Patch summary:
patch-1: ensures that compiler optimization doesn't occur on vq->broken
         flag
patch-2: maintains the mirror sequence on VQ delete and VQ create
patch-3: protects vqs list for simultaneous access from reader and a writer
patch-4: handles surprise removal of virtio pci device which avoids
         call trace and system lockup

Any comments to address or will you please take this short series?

I am working on improving other part of the hotplug that you described to take care in near future. (next kernel cycle).
