What's the rough ETA for all the subpage-blocksize prerequisities? We've
agreed at LSF to postpone any major refactoring and cleanups until the
patchset lands but with more dependencies I think the current subpage
patches would need to be rewritten from scratch anyway.
Delaying for one or two more major releases still sounds doable, but
with current pace of changes I'm afraid that's unrealistic and will just
block other work.
