[PATCH perf/core v10 00/23] perf-probe --cache and SDT support

[Masami Hiramatsu]

Hi,

Here is the 10th version of the patchset for probe-cache and 
initial SDT support.

This version fixes a bug and split big patches into small subsets
according to Namhyung's comment.
Also I've added a testcase for SDT. In this version, the number of
patches are increased, but basically, only 3 patches (bugfix, and
adding test) are new.

Changes in v10:
  - [1/23] Fix a bug in rm_rf().
  - [2/23,] Separate a big patch into 3 sub patches.
  - [3/23 - 7/23] separate a big patch into 5 sub patches.
  - [13/23, 14/23] Update documents for SDT explanations.
  - [22/23, 23/23] Add a test case for SDT and update build config
    to detect sys/sdt.h.

Thank you,
