> Subject: [PATCH v6 0/3] provide thread unsafe async registration functions
>
> Lock protection is needed during the vhost notifies the application of
> device readiness, so the first patch adds lock protection. In addition,
> the second patch reworks async feature structure to improve readability.
> After performing locking, existed async vhost registration functions will
> cause deadlock, as they acquire lock too. The last patch provides thread
> unsafe registration functions to support calling within vhost callback
> functions.
