Take first steps to split up fs.h. Add fs_super_types.h and fs_super.h
headers that contain the types and functions associated with super
blocks respectively.

We have this nice concept called directories for namespace prefixes.
Why not include/linux/fs/*.h for all these split out bits?

Sure, fine by me. Some do it differently. For example, mm has mm_* too.
But yeah, the fs/ layout is fine.

/me raises eye-brows:

blk-cgroup.h          blkdev.h              blk-mq.h              blktrace_api.h
blk-crypto.h          blk-integrity.h       blkpg.h               blk_types.h
blk-crypto-profile.h  blk-mq-dma.h          blk-pm.h

What sort of mix-and-match bonanza have you got going on over there?
