[PATCH perf/core v4 0/4] perf-probe: Add filtering features

[Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com>]

Hi,

Here is a series of patches which improves perf-probe to add
filtering features for --del and --funcs, and cleanup code.

This version is just updated for the latest perf/core.

--del and --funcs accepts filter rules too which is more flexible
than simple wildcard.
  ----
  # ./perf probe -d 'vfs*|malloc'
  Removed event: probe:vfs_read
  Removed event: probe_libc:malloc
  ----

Changes in v4:
  - Removes patches which already merged.
  - [1/4] Update for the latest perf/core.

Changes in v3:
  - [1/8] Split strfilter__or() and add strfilter__and() from v2 [3/8].
           Also rename strfilter__add() to strfilter__append().
  - [2/8] Split strfilter__string from v2 [5/8].

Changes in v2:
  - [2/8] Fix to check errors except -ENOENT on deleting events.
  - [5/8] Ditto.
  - [5/8] Fix to check memory allocation error in strfilter__string.
  - [5/8] Fix to check errors of strfilter__string for verifying
          given filter.

Thank you,
