-         This option causes latency information to be gathered on local
-         caching and exported through file:
-
-               /proc/fs/fscache/histogram
-
-         The generation of this histogram adds a certain amount of overhead to
-         execution as there are a number of points at which data is gathered,
-         and on a multi-CPU system these may be on cachelines that keep
-         bouncing between CPUs.  On the other hand, the histogram may be
-         useful for debugging purposes.  Saying 'N' here is recommended.
