From 64e290ec69be39f1887fa0b403c1e417b6b038e7 Mon Sep 17 00:00:00 2001 From: Venkatesh Pallipadi Date: Thu, 4 Mar 2010 22:25:21 -0500 Subject: ext4: fix up rb_root initializations to use RB_ROOT ext4 uses rb_node = NULL; to zero rb_root at few places. Using RB_ROOT as the initializer is more portable in case the underlying implementation of rbtrees changes in the future.
