From d44651d0f922b7aaeddd9fc04f2f5700a65983dd Mon Sep 17 00:00:00 2001 From: Fabrice Jouhaud Date: Sat, 8 Oct 2011 16:26:03 -0400 Subject: [PATCH] ext4: fix ext4 so it works without CONFIG_PROC_FS This fixes a bug which was introduced in dd68314ccf3fb. The problem came from the test of the return value of proc_mkdir which is always false without procfs, and this would initialization of ext4.
