Assuming I understand your discussion, I see two ways to go, one is to
pass around fs specific state and continue to call into the FS many
times, and the other is to instead provide the fs with helper functions
that accomplish readahead calculation, page allocation, etc., and let
the FS keep its state naturally without having to preserve it in some fs
defined structure. The second approach would be cleaner code design,
that would also ease cross-os porting of filesystems, in my view.
