[Ocfs2-devel] [PATCH 07/18] ocfs2: Handles missing configfs_depend_item() and configfs_undepend_item()

[Sunil Mushran]

Mainline commit 631d1febab8e546e3bb800bdfe2c212b8adf87de added configfs_depend_item()
and configfs_undepend_item(). Patch adds empty macros when building against EL5 that
does not have the functionality.
