From 1dee3f59a8d5e711797dc82628aaf94a64e99922 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Mon, 9 May 2016 11:40:20 +0200 Subject: block/drbd: align properly u64 in nl messages The attribute 0 is never used in drbd, so let's use it as pad attribute in netlink messages. This minimizes the patch. Note that this patch is only compile-tested. Signed-off-by: Nicolas Dichtel Signed-off-by: Lars Ellenberg Signed-off-by: David S.
