Description of problem: There are a number of "editorial ocmments" on the latency tracer howto. Can I please have someone respond to the issues raised in order to finish this chapter. Assigned to Clark for distribution :) LKB
Lana, the Latency Tracer functionality is being rewritten by Steven Rostedt. I can think of no one better equipped to provide content. Reassigning to srostedt. Clark
Thanks Clark. Steven, in your re-write, can you please explain the statement below for me too? "Another way of using the tracing infrastructure is by enabling /proc/sys/kernel/trace_user_triggered. That will trace only processes that explicitly used the prctl(0, 1) syscall just before the critical session where tracing is desired and prctl(0, 0) after it." I don't really understand what effect the prctl() calls have on both the process and the tracer. Thanks, Lana
Steven, This is a friendly reminder :) LKB
