From 107ed40bd070df5e4a0a012042c45c40963dc574 Mon Sep 17 00:00:00 2001 From: Louis Rilling Date: Mon, 16 Jun 2008 19:01:00 +0200 Subject: [PATCH] configfs: Make configfs_new_dirent() return error code instead of NULL This patch makes configfs_new_dirent return negative error code instead of NULL, which will be useful in the next patch to differentiate ENOMEM from ENOENT.
