Subject[PATCH 0/3] tracing: histogram internals doc, hist_debug, and misc
Date
Hi Steve,

Here's the histogram internals documentation I promised awhile back
(second patch).

Accompanying it is a new config option that enables a new hist_debug
event file, which is used by the examples in the doc to display
some of the histogram internals (third patch).

The first patch is just a cleanup suggested by Masami that I
previously missed.

Thanks,

Tom
