- When handling perf_event_open() returning EBUSY and not being able to opendir
the procfs mount point we would tell the user that the oprofile daemon was
found by returning -1 on as the return for a bool function, oops, fix it,
found with Coccinelle (Peter Senna Tschudin).
- Fix per-pkg event reporting bug in 'perf stat' (Stephane Eranian)
Developer visible:
- Fix missing prototype for function provided when it isn't present in the
libelf present, fixing the build on RHEL/CentOS 5.1 systems, for instance
(Arnaldo Carvalho de Melo)
- Detect if the gcc and libnuma have the features needed to avoid requiring
the use of NO_LIBNUMA and/or NO_AUXTRACE to build on older systems
