From 8fafabd86f1b75ed3cc6a6ffbe6c3e53e3d8457d Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Tue, 28 Mar 2006 16:11:05 -0800 Subject: [PATCH] [PATCH] remove add_parent()'s parent argument add_parent(p, parent) is always called with parent == p->parent, and it makes no sense to do it differently. This patch removes this argument. No changes in affected .o files. Signed-off-by: Oleg Nesterov Cc: "Eric W.
