From fdadd54db5e9f05e673eb08746bf2bea460d9f0d Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 30 Jan 2008 13:31:56 +0100 Subject: [PATCH] x86: x86 ptrace generic requests This removes duplicated code by calling the generic ptrace_request and compat_ptrace_request functions for the things they already handle.
