Subject: [PATCH 4/6] IB/rdmavt: use kmalloc_array_node
Date: Wed, 27 Sep 2017 10:20:36 +0200
Message-ID: <20170927082038.3782-5-jthumshirn@suse.de> (raw)
In-Reply-To: <20170927082038.3782-1-jthumshirn@suse.de>
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.
