pub fn address_space_membarrier_state(
__arg0: AddressSpaceHandle,
) -> AddressSpaceMembarrierStateExpand description
Loads the shared mm identity and membarrier registration state.
This operation runs while rq locks or local IRQ exclusion may be held. It must be a fixed, allocation-free atomic lookup and must not acquire an OS lock or re-enter ax-task. An invalid handle is a fatal provider invariant.
