[PATCH 1/2] tracing: introduce TRACE_EVENT_FN_COND macro

2015-11-24 Thread Denis Kirjanov
TRACE_EVENT_FN can't be used in some circumstances like invoking trace functions from offlined CPU due to RCU usage. This patch adds the TRACE_EVENT_FN_COND macro to make such trace points conditional. Signed-off-by: Denis Kirjanov --- include/linux/tracepoint.h | 4 include/trace/define
