One comment still regarding to lli types. We can avoid warnings by
using (__force u32) in macros.

But that won't give the benefits of having the types checked.

You mean if we access the lli->field directly? I didn't quite get what
use case you are keeping in mind.

Yes, accessing any of those fields directly with my patch gives a sparse
warning.  It's situations like these those checks are intended for.
Defeating them seems foolish to me.

Otherwise it makes that struct looks ugly.
Why not union, though it still ugly, but less.
