Colin Cross b1ce49b2ed atrace: avoid unnecessary writes to trace_clock ... Writing to trace_clock erases the trace buffer, even if the value hasn't changed. This prevents use of --async_start and --async_dump to leave background tracing running and dump after an even that needs debugging, because --async_dump writes to trace_clock and resets the buffer before it can read it. Read and parse the current value from trace_clock before writing, and skip the write if the value isn't changing. Change-Id: Ia2ec5bb654fb0bd179771b511ff261731ba47dca		2014-08-20 14:28:47 -07:00
