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



The following changes since commit 8e99cf91b99bb30e16727f10ad6828741c0e992f:

tracing: Do not allocate buffer in trace_find_next_entry() in atomic (2020-04-03 11:30:50 -0400)

are available in the Git repository at:

git:// ftrace/hist-design-doc-v1

Tom Zanussi (3):
tracing: Check state.disabled in synth event trace functions
tracing: Add histogram-design document
tracing: Add hist_debug trace event files for histogram debugging
