[PATCH perf/core v6 00/14] perf-probe --cache and SDT support

[Masami Hiramatsu]

Hi,

Here is the 6th version of the patchset for probe-cache and 
initial SDT support.

The previous version is here; https://lkml.org/lkml/2016/4/27/828

This version fixes some bugs according to reviews and bugs found
by tests.

 Changes in v6:
  - [01/14] Replace local __is_regular_file with is_regular_file in util.c
    (Thank you Namhyung!)
  - [01/14] Fix dso__build_id_is_kmod() to check symlink in buildid cache
    correctly.
  - [03/14] Remove unneeded O_APPEND from open(). (Thanks Namhyung!)
  - [03/14] Fix to check the return value of probe_cache_entry__new and
     strdup.(ditto)
  - [04/14] Remove fallback lookup routine by using function name
    as cached event name, because it should be done by following
    patch which supports %cached-event.

Thank you,

---
