What version of Go are you using (go version)?

What operating system and processor architecture are you using (go env)?

What did you do?

I look at Go sources and see incorrect argument passing to sys_prlimit64 Linux syscall:

https://github.com/golang/go/blob/master/src/syscall/zsyscall_linux_386.go#L767

https://github.com/golang/go/blob/master/src/syscall/zsyscall_linux_amd64.go#L767

etc

    _, _, e1 := RawSyscall6(SYS_PRLIMIT64, uintptr(pid), uintptr(resource), uintptr(unsafe.Pointer(old)), uintptr(unsafe.Pointer(newlimit)), 0, 0)

What did you expect to see?

newlimit MUST be passed first, old must be passed next.

    _, _, e1 := RawSyscall6(SYS_PRLIMIT64, uintptr(pid), uintptr(resource), uintptr(unsafe.Pointer(newlimit)), uintptr(unsafe.Pointer(old)), 0, 0)

see Linux kernel source tree for example:

asmlinkage long sys_prlimit64(pid_t pid, unsigned int resource,
                const struct rlimit64 __user *new_rlim,
                struct rlimit64 __user *old_rlim);

What did you see instead?
