[PATCH 0/2 v3] tracing/histogram: Add buckets to group data in

[Steven Rostedt <rostedt@goodmis.org>]

Add a .buckets modifier to group the data instead of having every key saved
in its own entry, and in a linear fashion instead of like the log2 modifier.

Changes since v2:

 - Rename "grouping" field in hist_field to "buckets"
 - Updated documentation to describe the new modifier


Steven Rostedt (VMware) (2):
      tracing: Add linear buckets to histogram logic
      tracing/histogram: Update the documentation for the buckets modifier
