pub fn cancel_kernel_timer(
handle: KernelTimerHandle,
) -> Result<KernelTimerCancelOutcome, TaskError>Expand description
Cancels a registration without waiting for a callback already claimed.
CancellationDeferred accepts destruction and suppresses callback restart,
but is not a callback-completion or payload-reclamation barrier.
A remote cancellation mutates only the original owner base. It may leave a conservative stale hardware edge; only the owner CPU may reprogram its physical comparator.
