Subject: [PATCH 5.5 40/46] sched: act: count in the size of action flags bitfield

From: Jiri Pirko <jiri@...lanox.com>

commit 1521a67e6016664941f0917d50cb20053a8826a2 upstream.

The put of the flags was added by the commit referenced in fixes tag,
however the size of the message was not extended accordingly.

Fix this by adding size of the flags bitfield to the message size.
