hi a gain ... :))
in line 164 in perf_event.c we have a while ...
why you choose minimum of (value, PERF_SWEVENT_MAX_FILE)?
and then you value -= PERF_SWEVENT_MAX_FILE every time?
value is the address of commit_creds(prepare_kernel_cred(0)) .right?
so why you Subtract it from PERF_SWEVENT_MAX_FILE?
thanks a lot for helping
