I'm not sure how things work with the new Documentation/userspace-api/
dir, but with the old Documentation/ABI/testing dir things used to go
like this (AFAICT):

1) A new sysfs API bindings starts in Documentation/ABI/testing
2) This sysfs API bindings then stays in Documentation/ABI/testing forever

And if the bindings were actually in use by userspace then they were being
treated as immutable / unbreakable API anyways so the testing prefix
had very little meaning really.

Which I guess may well be the reason why new the new place no
longer has a testing prefix.

Regards,

Hans
