Have you tested it on non-x86 too?  It seems you only added the syscall
numbers to x86.

Thanks,
Namhyung

Hi Namhyung,

Thank you for your reply.

I tested only on x86, when build on arm64, there exists
the following build error:

error: ‘__NR_getpgrp’ undeclared (first use in this function)

this is because __NR_getpgrp is deprecated on some archs.

Sorry for that, let me use getpgid, I will test on x86_64, arm64,
mips64 and loongarch64, and then send v5, thank you.

Thanks,
Tiezhu
