From 64fb4eb7d4cc9de89f4d9b9061adde46ed3b5641 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 18 Jan 2006 13:14:40 +0000 Subject: [GFS2] Remove gfs2_databuf in favour of gfs2_bufdata structure Removing the gfs2_databuf structure and using gfs2_bufdata instead is a step towards allowing journaling of data without requiring the metadata header on each journaled block. The idea is to merge the code paths for ordered data with that of journaled data, with the log operations in lops.c tacking account of the different types of buffers as they are presented to it. Largely the code path for metadata will be similar too, but obviously through a different set of log operations.
