Agree with Ville here, we want subtests for all the cursor sizes we
support and to correctly skip them if the kernel doesn't accept a cursor
of a given size. Once that's all ready your cursor sizes patch is imo good
to go.
Please don't forget to add a Testcase: tag to your kernel patch
referencing your new (sub)tests here.
Thanks, Daniel
