> Subject: [PATCH v2 00/15] vhost: clean-up and simplify async implementation
>
> This series aims at cleaning and simplifying the async enqueue path. I think
> it
> makes the code easier to understand, and is necessary before integrating
> new changes.
>
> I may have more reworks to propose in next revisions, but I wanted to share
> my current status early so that you have time to review/test it.
>
> It is only compile-tested, as I don't have HW with IOAT support to test it.
>
> Changes in v2:
> ==============
> - Print once when max number of iovec is reached (Jiayu)
> - Increase number of IOVECs from 512 to 2048 (Jiayu)
> - Fix Vhost example build when raw/ioat is disabled
>
> Changes in v1:
> ==============
> - Fix missing iovec index increment (Jiayu)
> - Remove unneeded sanity check on IOV iter index (Jiayu)
> - Fix async->pkts_info allocation check (Jiayu)
> - Prevent NULL pointer dereference on async metadata cleanup (Jiayu)
