Shouldn't this be in include/uapi/linux/fs_types.h?
One of things which must be made crystal clear is these definitions
MUST NOT ever change. It would break the Userspace ABI, and would
break file systems on-disk format.
It might also be useful to be clear *why* we are making this change in
the first place. Code refactorization is good from a code maintenance
perspective (either to fix bugs, although this code is pretty
trivial), or to make it easier to make changes in a single central
place (which MUST NOT) happen, or to make the compiled code more
compact.
So some documentation of how much text is actually saved might be
worthwhile.
