Struct AddressSpaceMembarrierState 

pub struct AddressSpaceMembarrierState { /* private fields */ }

Allocation-free snapshot of one address space’s membarrier state.

Implementations

impl AddressSpaceMembarrierState

pub const NONE: Self

State installed for a kernel thread without a userspace mm.

pub const unsafe fn new(identity: AddressSpaceMembarrierId, bits: u32) -> Self

Constructs a provider snapshot from one live shared mm identity.

Safety

identity must obey AddressSpaceMembarrierId::from_raw, and bits must contain only requested and ready bits produced by MembarrierRegistration.

pub const fn identity(self) -> AddressSpaceMembarrierId

Returns the shared address-space identity.

pub const fn requested(self, registration: MembarrierRegistration) -> bool

Reports whether registration has begun, including its synchronization interval before the ready bit becomes visible.

pub const fn ready(self, registration: MembarrierRegistration) -> bool

Reports whether registration completed its rq synchronization.

pub const fn any_requested(self) -> bool

Reports whether any scheduler-visible membarrier facility is active.

pub const fn bits(self) -> u32

Returns the provider-owned atomic representation.
