Re: [RFC-PATCH v2] vhost-user: add a request-reply lock

Hello Michael, all

Sorry about a late reply,  catching up with emails after long PTOs.

* Yes, okay. Thank you for the review. I sent in reply to v1 because
this is a 'RFC' thread and there was no review yet to this series.

* If  this V2 patch looks reasonable/acceptable, I'll send this series
for review (without RFC) as V2, if that's okay.

* Going through the git logs, vhost_user_set_log_base() sends set log
message only when vq_index==0, so the above patch is not required
IIUC.
