Intentional asymmetry: the kobj only exposes ops, events and caps, and a
sub's caps come from parent grants at runtime, not from its own
ops.init(). The pshard cmasks that caps reads are allocated and zeroed
before the sysfs add, so a pre-init read shows the truthful "no caps
yet". Root defers past ops.init() because it seeds its own caps there.
No change.

Thanks.
