New NOTIFY system call! Queued at kernel. Duplicate messages (with same source
...
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.
