From c97d98931ac52ef110b62d9b75c6a6f2bfbc1898 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Tue, 28 Mar 2006 16:11:06 -0800 Subject: [PATCH] kill SET_LINKS/REMOVE_LINKS Both SET_LINKS() and SET_LINKS/REMOVE_LINKS() have exactly one caller, and these callers already check thread_group_leader(). This patch kills theese macros, they mix two different things: setting process's parent and registering it in init_task.tasks list. Callers are updated to do these actions by hand.
