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. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
