From 4c5d6edeb2b10c2044d1ea2b4fa3e403133431c8 Mon Sep 17 00:00:00 2001
From: Dmitri Goutnik <dgoutnik@gmail.com>
Date: Wed, 22 Feb 2023 10:58:14 -0500
Subject: [PATCH] syscall: add ptracePtr that accepts pointer arg as
unsafe.Pointer
The existing ptrace wrapper accepts pointer argument as an uintptr which
often points to the memory allocated in Go. This violates unsafe.Pointer safety
rules.
Fixes #58387
