Any reason why this can't use a generic function such as
__set_page_dirty_nobuffers? There are accounting changes gone in
there now which I suspetc may be wrong now in reiser4 (eg. task
io accounting).
Actually every site that does a radix_tree_operation there should
be reviewed to try to use core functoins.
