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?

Can we please proceed with these series?

We want users to stop facing the call trace and lockup.
Can you please respond to this short series?
