From: Masami Hiramatsu
Date: Sat May 28 2016 - 11:15:33 EST


Hi,

Here is the 9th version of the patchset for probe-cache and
initial SDT support.

The previous version is here; https://lkml.org/lkml/2016/5/14/107

This version just fixes 2 points according to Hemant's comment,
and split out the filename__readable() patch.

Changes in v9:
- [1/16,2/16] split out the filename__readable()
- [7/16] Fix to show which event is deleted.
- [12/16] Update list_usage to show sdt option.

Thank you,

---
