From 9cd1f701ce47599ddfb589afeb88b5513b6915bc Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Thu, 6 Jul 2017 15:40:37 -0700 Subject: [PATCH] mm/zswap.c: improve a size determination in zswap_frontswap_init() 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.
