Thread-topic: [Xen-devel] [PATCH 2/3] blktap: mb fixes
User-agent: Microsoft-Entourage/11.2.5.060620
Applied, except for one chunk which added a barrier before update of
req_cons. This was not mentioned in the changeset comment and I do not
believe there is any race that needs fixing (certainly not between memcpy of
request data and read of req_cons in make_response()). I applied the rest of
the patch as-is.
