From: Pankaj Gupta <pankaj.gupta@ionos.com>
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.
