 Jeff reported preflush order issue with the existing implementation
 of virtio pmem preflush. Dan suggested[1] to implement asynchronous flush
 for virtio pmem using work queue as done in md/RAID. This patch series
 intends to solve the preflush ordering issue and also makes the flush
 asynchronous for the submitting thread.

 Submitting this patch series for review. Sorry, It took me long time to
 come back to this due to some personal reasons.

 RFC v1 -> RFC v2
 - More testing and bug fix.
