You didn't cc the patches to me, and I can't find patch 3/3 at all.

I don't think the KSA() macro should be casting its argument. Where the
cast is necessary, it ought to be explicit in the caller.

Similarly I think the BUILD_BUG_ON() in ksa_build_check() doesn't belong
there, but in whichever caller of ksa_parse_ints() requires struct
ksmall_array to have the same layout as a simple array of unsigned int.
