The patch titled
Subject: mm/zswap: delete unnecessary check before calling free_percpu()
has been removed from the -mm tree. Its filename was
mm-zswap-deletion-of-an-unnecessary-check-before-the-function-call-free_percpu.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Subject: mm/zswap: delete unnecessary check before calling free_percpu()
free_percpu() 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.
