Subject: [PATCH] fixup! vhost: extend memory regions allocation to vmalloc
Date: Wed, 15 Jul 2015 16:48:50 +0200 [thread overview]
Message-ID: <1436971730-277452-1-git-send-email-imammedo@redhat.com> (raw)
callers of vhost_kvzalloc() expect the same behaviour on
allocation error as from kmalloc/vmalloc i.e. NULL return
value. So just return vzmalloc() returned value instead of
returning ERR_PTR(-ENOMEM)
