[PATCH 0/4 perf-tools-next] perf ftrace latency linear buckets

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Hi,

	Gabriele has been using 'perf ftrace latency' in some
investigations at work and wanted to have an alternative way of
populating the buckets, so we came up with this series, please take a
look at the examples provided in the changesets.

Thanks,

- Arnaldo

Arnaldo Carvalho de Melo (3):
  perf ftrace latency: Pass ftrace pointer to histogram routines to pass more args
  perf ftrace latency: Introduce --bucket-range to ask for linear bucketing
  perf ftrace latency: Introduce --min-latency to narrow down into a latency range

Gabriele Monaco (1):
  perf ftrace latency: Add --max-latency option
