perf probe: Fix probe_point buffer overrun
Fix probe_point array-size overrun problem. In some cases (e.g. inline function), one user-specified probe-point can be translated to many probe address, and it overruns pre-defined array-size. This also removes redundant MAX_PROBES macro definition. Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Cc: systemtap <systemtap@sources.redhat.com> Cc: DLE <dle-develop@lists.sourceforge.net> Cc: <stable@kernel.org> LKML-Reference: <20100312232217.2017.45017.stgit@localhost6.localdomain6> [ Note that only root can create new probes. Eventually we should remove the MAX_PROBES limit, but that is a larger patch not eligible to perf/urgent treatment. ] Signed-off-by: Ingo Molnar <mingo@elte.hu>
