SubjectRe: [RFC] Splitting kernel headers and deprecating __KERNEL__
	Speaking of include/* cleanups, here's a work of about 10 minutes
(and yes, result does build):
*	private stuff moved into fs/affs/affs.h
*	include/linux/affs_fs_{i,sb}.h removed, since they do not contain
anything that might be used outside of fs/affs/*
*	includes in fs/affs/* trimmed (as the matter of fact, only super.c
needed something not pulled by affs.h)
*	duplicate MODULE_LICENSE removed from fs/affs/inode.c (fs/affs/super.c
already has exact same thing)
*	bogus extern (affs_fs()) removed (used to be in affs_fs.h, function
in question simply doesn't exist)
That leaves affs_fs.h containing only AFFS_SUPER_MAGIC declaration and
amigaffs.h also seriously cleaned up; it still has a bunch of defines that
are almost certainly never used in userland (they refer to ->b_data and
in-core affs superblock), but these might in theory be useful (similar
stuff for ext2 *is* used by userland code).

If Roman is OK with their removal, AFFS_DATA and friends should also get
moved to fs/affs/affs.h.
