Something that you may be unaware of is that the introduction of the sgl
helper functions is only a first step. The next step will be to introduce
a caching allocator for sg-lists. So for small sg-lists inlining won't
help performance. But moving these definitions from a .c file into a .h
file will (slightly) slow down kernel compilation. So I'd prefer that you
drop this patch.

Thanks,

Bart.
