From ccebd4c4159462c96397ae9af9c667bb394d7b70 Mon Sep 17 00:00:00 2001 From: Jonathan Brassow Date: Fri, 14 Jan 2011 09:14:33 +1100 Subject: md-new-param-to_sync_page_io Add new parameter to 'sync_page_io'. The new parameter allows us to distinguish between metadata and data operations. This becomes important later when we add the ability to use separate devices for data and metadata.
