cyclictest: Remove duplicated description of cyclictest usage like -h.
Author: Lim,GeunSik <leemgs1@gmail.com> Date: Tue Apr 21 16:03:56 2009 +0900 [PATCH] cyclictest: Remove duplicated description of cyclictest usage like -h. We often utilize a various options with "#>cyclictest --help" command in the terminal environment. When We run "#> cyclictest --help" command, We can show duplicated description about "-h" option for latency histogram. Unfortunatley, Some of the users is confusing because of two options about latency histogram. [root@fedora9 invain]# ./cyclictest --help cyclictest V 0.36 Usage: cyclictest <options> -a [NUM] --affinity run thread #N on processor #N, if possible with NUM pin all threads to the processor NUM -b USEC --breaktrace=USEC send break trace command when latency > USEC -B --preemptirqs both preempt and irqsoff tracing (used with -b) -c CLOCK --clock=CLOCK select clock 0 = CLOCK_MONOTONIC (default) 1 = CLOCK_REALTIME -C --context context switch tracing (used with -b) -d DIST --distance=DIST distance of thread intervals in us default=500 -E --event event tracing (used with -b) -f --ftrace function trace (when -b is active) -h H_MAX latency histogram size in us default 0 (off) -i INTV --interval=INTV base interval of thread in us default=1000 ................. [Middle Omission] ................... -v --verbose output values on stdout for statistics format: n:c:v n=tasknum c=count v=value in us -D --duration=t specify a length for the test run default is in seconds, but 'm', 'h', or 'd' maybe added to modify value to minutes, hours or days -h --histogram=US dump a latency histogram to stdout after the run US is the max time to be be tracked in microseconds For example, -h H_MAX latency histogram size in us default 0 (off) -h --histogram=US dump a latency histogram to stdout after the run US is the max time to be be tracked in microseconds As you see, We don't need "-h H_MAX . . . . . ." description. So, I think that We have to remove old option about description of histogram function. Signed-off-by: GeunSik Lim <leemgs1@gmail.com>
