From e96a650a8174e20112b400e72e0b2429aa66de20 Mon Sep 17 00:00:00 2001 From: SF Markus Elfring Date: Sun, 2 Nov 2014 15:20:59 +0100 Subject: ceph, rbd: delete unnecessary checks before two function calls The functions ceph_put_snap_context() and iput() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
