Actually, regarding -rt, we try to keep that in two buckets:

 1) Normal kernel code works but is unclean or structured less
    than ideal. In this case we restructure the mainline code,
    but that change stands on its own four legs, without any
    -rt considerations.

 2) Normal kernel code that is clean - i.e. a change that only
    matters to -rt. In this case we dont touch the mainline code,
    nor do we bother mainline.

Do you know any specific example that falls outside of those categories?
