[Cluster-devel] [PATCH 1/2] dlm: cleanup remove unused code

[David Teigland]

From: Dan Carpenter <error27 at gmail.com>

Smatch complains because "lkb" is never NULL.  Looking at it, the original
code actually adds the new element to the end of the list fine, so we can
just get rid of the if condition.  This code is four years old and no one
has complained so it must work.
