* Description:
* echo a 0 or a 1 into perf_counter_reset to
* reset all the counters in
* /sys/fs/orangefs/perf_counters
* except ones with PINT_PERF_PRESERVE set.
*
*
* What: /sys/fs/orangefs/perf_counters/...
* Date: Jun 2015
* Contact: Mike Marshall <hubcap@omnibond.com>

* Read only.
*
*
* What: /sys/fs/orangefs/perf_time_interval_secs
* Date: Jun 2015
* Contact: Mike Marshall <hubcap@omnibond.com>
* Description:
* Length of perf counter intervals in
* seconds.
*
*
* What: /sys/fs/orangefs/perf_history_size
* Date: Jun 2015
* Contact: Mike Marshall <hubcap@omnibond.com>
* Description:
* The perf_counters cache statistics have N, or
* perf_history_size, samples. The default is
* one.
*
* Every perf_time_interval_secs the (first)
* samples are reset.
*
* If N is greater than one, the "current" set
* of samples is reset, and the samples from the
* other N-1 intervals remain available.
