From c413af877ffa8a8c28796c9d156cf40a83e58994 Mon Sep 17 00:00:00 2001 From: Johannes Thumshirn Date: Wed, 15 Nov 2017 17:32:49 -0800 Subject: [PATCH] net/rds/ib_fmr.c: use kmalloc_array_node() Now that we have a NUMA-aware version of kmalloc_array() we can use it instead of kmalloc_node() without an overflow check in the size calculation.
