> 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.
>
> v6:
> * remove RTE_VHOST_ASYNC_FEATURE_UNKNOWN
> * add blank lines in doc
> v5:
> * improve coding style
> * update commit log, doc and comments
> * remove useless field async_inorder
> * change async_threshold from uint16_t to uint32_t
> v4:
> * remove brace {} in single statement block
> v3:
> * rename and use enum to define async device features
> * change padding fields to 8 bytes
> v2:
> * rework async feature structure
> * fix typo in commit log
>
> Jiayu Hu (3):
> vhost: fix lock on device readiness notification
