Functions
auto	zxfoundation::smp::csd::call_function_many (const ::lib::cpumask &mask, csd_fn func, void *data, u64 info, call_single_data *csd_pool, u32 pool_capacity) noexcept -> std::expected< u32, lib::kernel_error >
	Fan-out a synchronous callback to many CPUs at once.
auto	zxfoundation::smp::csd::call_function_single_async (u16 cpu, call_single_data *csd) noexcept -> std::expected< void, lib::kernel_error >
	Enqueue a pre-initialised csd onto a target CPU.
auto	zxfoundation::smp::csd::call_function_single_sync (u16 cpu, csd_fn func, void *data, u64 info) noexcept -> std::expected< void, lib::kernel_error >
	Synchronous single-CPU function-call IPI.
auto	zxfoundation::smp::csd::disable_cpu (u16 cpu) noexcept -> void
	Prevent new remote CSD enqueues to cpu and wait until all already accepted callbacks have completed on the target.
auto	zxfoundation::smp::csd::drain_cpu () noexcept -> void
	Drain all pending CSD nodes for the running CPU.
auto	zxfoundation::smp::csd::enable_cpu (u16 cpu) noexcept -> void
	Allow remote CSD enqueues to cpu after it has been initialized.
auto	zxfoundation::smp::csd::init (call_single_data &csd, csd_fn func, void *data, u64 info, u32 flags) noexcept -> void
	Initialise a csd before enqueue.
auto	zxfoundation::smp::csd::is_done (const call_single_data &csd) noexcept -> bool
	Test whether csd has completed dispatch.
auto	zxfoundation::smp::csd::lock_wait (const call_single_data &csd) noexcept -> void
	Wait until the target CPU has completed dispatch of csd.
auto	zxfoundation::smp::csd::pending () noexcept -> bool
	Test whether the running CPU has any pending csd nodes.
auto	zxfoundation::smp::csd::set_rcu_free (call_single_data &csd, void(*fn)(sync::rcu::rcu_head *) noexcept) noexcept -> void
	Register an RCU-freeing callback on a csd flagged with CSD_F_RCU_FREE.
auto	zxfoundation::smp::csd::stats_of (u16 cpu) noexcept -> csd_stats
	Read the per-CPU CSD statistics block for diagnostics.
