Function fast_send

pub fn fast_send(msg: &SmallMessage, target_pid: u64) -> Result<()>
Expand description

Fast path IPC send for small messages

Copies the message directly into the target task’s ipc_regs array if the target is blocked waiting for a message. This avoids all intermediate queuing and achieves sub-microsecond latency.
