SubjectRe: [RFC v2 0/2] virtio-pmem: Asynchronous flush
Gentle ping.

>
> 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.
