The riddle:
1. If the operating system being used is Linux, what other mechanisms
(besides turning off interrupts) are available to single-processor
systems to accomplish this?
2. If the system has a multi-core processor or several processors, which
low overhead synchronization method can be used to accomplish this?
Read in Linux Device Drivers how to implement a queue with no locks. You
don't need the data access to be atomic, so long as the queue pointer
can be accessed atomically.
