Enables or disables eager check I/O scheduling. Defaults
- to
The flag effects when schedulers will check for I/O
- operations possible to execute, and when such I/O operations
- will execute. As the parameter name implies,
- schedulers are more eager to check for I/O when
-
Sets scheduler-forced wakeup interval. All run queues are
