That's not what I meant. There's a kerneldoc comment on vfs_get_block_super() that you need to modify. I would in any case roll your patch into mine. > This is intended for gfs2 to select between the normal root and the > 'meta' root, which must be done whether a root already exists for a > superblock or not, i.e. it cannot be decided in fill_super(). Can this be done in gfs2_get_tree, where it sets fc->root? David
