The patch titled
Subject: ocfs2: delete unnecessary checks before three function calls
has been removed from the -mm tree. Its filename was
ocfs2-deletion-of-unnecessary-checks-before-three-function-calls.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Subject: ocfs2: delete unnecessary checks before three function calls
kfree(), ocfs2_free_path() and __ocfs2_free_slot_info() test whether their
argument is NULL and then return immediately. Thus the test around their
calls is not needed.
This issue was detected by using the Coccinelle software.
