Subject[PATCH perf/core v4 0/4] perf-probe: Add filtering features
From
Date
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,


---
