[PATCH v2 3/3] tracing: add additional marks to signal very large delay

2014-11-04 Thread byungchul . park
From: Byungchul Park Currently, some tracers tracing latency print "!" or "+" just after time to signal overhead, depending on the interval between events. Even it is usually enough to do that, we sometimes need to be signaled for bigger interval than 100 micro seconds. Signed-off-by: Byungchul
