Subject: [PATCH] lib/rbtree: avoid pointless rb_node alignment
Date:   Fri, 10 Jan 2020 13:54:29 -0800
Message-Id: <20200110215429.30360-1-dave@stgolabs.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Now that Linux no longer supports the CRIS architecture,
we can drop this fishy alignment. Apparently this was
need to prevent misalignments in struct address_space.
