Subject: [PATCH] trace-cmd: Do not call stop_threads() if doing latency
|
|
tracing
|
|
|
|
Upstream-Status: Backport
|
|
|
|
If we are using a latency tracer we do not call start_threads() we
|
|
should therefore not call stop_threads() if 'latency'. Attempting
|
|
to call stop_threads() without first calling start_threads() will
|
|
cause a segfault since pids will be uninitialized.
