Subject: [PATCH net-next 0/4] net: extend indirect calls helper usage
Date: Fri, 3 May 2019 17:01:35 +0200 [thread overview]
Message-ID: <cover.1556889691.git.pabeni@redhat.com> (raw)
This series applies the indirect calls helper introduced with commit
283c16a2dfd3 ("indirect call wrappers: helpers to speed-up indirect
calls of builtin") to more hooks inside the network stack.
Overall this avoids up to 4 indirect calls for each RX packets,
giving small but measurable gain TCP_RR workloads and 5% under UDP
flood.
Paolo Abeni (4):
net: use indirect calls helpers for ptype hook
net: use indirect calls helpers for L3 handler hooks
net: use indirect calls helpers at early demux stage
net: use indirect calls helpers at the socket layer
