[net-next,0/3] Tracepoints for SMC

Message

Tony Lu Nov. 1, 2021, 7:39 a.m. UTC

This patch set introduces tracepoints for SMC, including the tracepoints
basic code. The tracepoitns would help us to track SMC's behaviors by
automatic tools, or other BPF tools, and zero overhead if not enabled.

Compared with kprobe and other dymatic tools, the tracepoints are
considered as stable API, and less overhead for tracing with easy-to-use
API.
