Before this patch, function gfs2_meta_sync called filemap_fdatawrite to write the address space for the metadata being synced. That's great for inodes, but resource groups all point to the same superblock-address space, sdp->sd_aspace. Each rgrp has its own range of blocks on which it should operate. That meant every time an rgrp's metadata was synced, it would write all of them instead of just the range. This patch eliminates function gfs2_meta_sync and tailors specific metasync functions for inodes and rgrps.
