Subject: [PATCH v14 07/74] xarray: Define struct xa_node
Date: Sat, 16 Jun 2018 18:59:45 -0700	[thread overview]
Message-ID: <20180617020052.4759-8-willy@infradead.org> (raw)
In-Reply-To: <20180617020052.4759-1-willy@infradead.org>

This is a direct replacement for struct radix_tree_node.  A couple of
struct members have changed name, so convert those.  Use a #define so
that radix tree users continue to work without change.
