For all patches:
Reviewed-by: NeilBrown <neilb@xxxxxxx>
Thanks Jeff - I think this is a good and useful change and while it
might not all be as pretty as I might like, I don't see any way to
improve it and think it is certainly good enough to merge.
I think the conversion from "fl_core" to "c" does work well enough.
I particularly like how the removal of the IS_* macros (patch 16) turned
out. The inline expansion of IS_LEASE() in particular makes the code
clearer to me.
Thanks,
NeilBrown
