[PATCH 01/11] ocfs2: Delete an unnecessary check before unregister_sysctl_table()

From: SF Markus Elfring
Date: Sun Jul 05 2015 - 09:27:27 EST

The unregister_sysctl_table() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
