2018-11-12 | kyber: fix wrong strlcpy() size in trace_kyber_latency() | Omar Sandoval | |
When copying to the latency type, we should be passing LATENCY_TYPE_LEN, not DOMAIN_LEN (this isn't a problem in practice because we only pass "total" or "I/O"). Fix it by changing all of the strlcpy() calls to use sizeof().

2018-09-27 | kyber: add tracepoints | Omar Sandoval | |
When debugging Kyber, it's really useful to know what latencies we've been having, how the domain depths have been adjusted, and if we've actually been throttling. Add three tracepoints, kyber_latency, kyber_adjust, and kyber_throttled, to record that. Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |
