    [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.
