Hmm, I didn't know such history...
Anyway I agree mmap approach in aufs is ugly in the terms of its logic
and looking. And I am afraid converting into macros looks still
bad-looking. Do you think can we do this?
- create a new file mm/aufs_mmap.c
- move the inline funcs to the new file.
- the calling macros are left in mm.h.
- function delarations are added in mm.h.

Is it necessary?
struct vm_regin is defined regardless CONFIG_MMU, isn't it?
