[PATCH perf/core 0/5] perf-probe bugfixes

Show all headers | View raw

Hi,

Here is a bunch of bugfix patches for perf-probe.

- Begin and end report session correctly, which fixes
  a mistake of libdwfl usage.
- Fix to remove dot suffix from second or latter events
  which fixes a bug on multiple events on a dot suffixed
  symbol.
- Show correct source lines of probes on kmodules, which
  fixes a bug that perf-probe --list can not find probe
  points in kernel modules.
- Fix a segfault bug in debuginfo_cache, which fixes a
  segfault bug in debuginfo_cache__open.
- Improve error message when %return is on inlined function
  is not actual bugfix, but improve an error message.


Thank you,
