From 85b6bce3658a823aa169586fe71ffba0f12ccc71 Mon Sep 17 00:00:00 2001 From: Pavel Machek Date: Fri, 31 Mar 2006 02:30:06 -0800 Subject: [PATCH] [PATCH] Fix suspend with traced tasks strace /bin/bash misbehaves after resume; this fixes it. (akpm: it's scary calling refrigerator() in state TASK_TRACED, but it seems to do the right thing).
