From 6b41fd1785f4effe2f3bd40da864415812f5b8c9 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 20 Jun 2006 19:44:03 -0700 Subject: [PATCH] Fix up CFQ scheduler for recent rbtree node shrinkage The color is now in the low bits of the parent pointer, and initializing it to 0 happens as part of the whole memset above, so just remove the unnecessary RB_CLEAR_COLOR.
