Subject: [PATCH 0/2 v3] tracing/histogram: Add buckets to group data in
Date: Wed, 07 Jul 2021 17:36:23 -0400	[thread overview]
Message-ID: <20210707213623.250212325@goodmis.org> (raw)

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
