Needs a bit of tweaking yet...  (apologies for not replying
earlier, there's just been more pressing things to work on).

These first changes aren't really useful; they make the DMAPI
code more difficult to integrate and manage in our trees, for
not-enough gain.

These are more useful - I'll merge these in, thanks.

OK, then the #define's have to stay.

Would it be OK to make vfs_dmapiops #ifdef on the DMAPI code?
