I'll test that out. Thanks for > testing, but I may have another patch soon.
OK, it's still broken there with this patch. I got this:
# ls /sys/kernel/tracing/events/syscalls enable filter sys_enter_nanosleep sys_exit_nanosleep
But with this:
return !strcmp(sym + 9, name + 3) || !strcmp(sym + 3, name + 3);
I get all the syscalls back. I'll make another patch.
