[PATCH] pid: Properly detect orphaned process groups in exit_notify
In commit 0475ac0845f9295bc5f69af45f58dff2c104c8d1 when converting the orphaned process group handling to use struct pid I made a small mistake. I accidentally replaced an == with a !=. Besides just being a dumb thing to do apparently this has a bad side effect. The improper orphaned process group detection causes kwin to die after a suspend/resume cycle. I'm amazed this patch has been around as long as it has without anyone else noticing something funny going on. And the following people deserve credit for spotting and helping to reproduce this.
