Hi Stephane,
As Carl Love and I were going over how unit masks are handled in libpfm, we ran
into a confusing looking profile for pfm_find_event_mask. The first argument is
the event index, and the doc shows it as a pointer to an unsigned int. The
actual code has this as just an unsigned int.
I've attaching a patch to fix this error (or what appears to be an error).
