[Cluster-devel] [PATCH 05/10] dlm: Improve a size determination in dlm_recover_waiters_pre()

From: Markus Elfring <[email protected]>
Date: Sat, 6 May 2017 08:48:29 +0200

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
