Merge branch 'RDS-optimized-notification-for-zerocopy-completion'
Sowmini Varadhan says:
====================
RDS: optimized notification for zerocopy completion
Resending with acked-by additions: previous attempt does not show
up in Patchwork. This time with a new mail Message-Id.
RDS applications use predominantly request-response, transacation
based IPC, so that ingress and egress traffic are well-balanced,
and it is possible/desirable to reduce system-call overhead by
piggybacking the notifications for zerocopy completion response
with data.
Moreover, it has been pointed out that socket functions block
if sk_err is non-zero, thus if the RDS code does not plan/need
to use sk_error_queue path for completion notification, it
is preferable to remove the sk_errror_queue related paths in
RDS.
Both of these goals are implemented in this series.
v2: removed sk_error_queue support
v3: incorporated additional code review comments (details in each patch)
