Yes, I know it's not an architectural change, more of a temporary
band-aid for better pointer
management, but fair, pointless for now.

I agree, the codebase is complicated, I definitely won't send any
changes at the moment
(unless they would be checkpatch.pl changes, which are low priority
ofc). However, the
iov_iter problem is intriguing and I'll surely spend some time working on it.
