Fastmap needs basically access to all internal state of UBI, which lives mostly within wl.c It needs to iterate over the used, free, erase, scrub RB-trees, the protection queue, etc. to collect the exact state of all PEBs.
In C++ or Java I would pass an iterator to fastmap.c using a function in wl.c but I'm not sure how to do such a thing in a sane way in C.
What about having a wl-fastmap.c file which acts as glue layer between fastmap.c and wl.c?
Thanks, //richard
