-/** \defgroup lnet_eq Events and event queues
- *
- * Event queues (abbreviated as EQ) are used to log operations performed on
- * local MDs. In particular, they signal the completion of a data transmission
- * into or out of a MD. They can also be used to hold acknowledgments for
- * completed PUT operations and indicate when a MD has been unlinked. Multiple
- * MDs can share a single EQ. An EQ may have an optional event handler
- * associated with it. If an event handler exists, it will be run for each
- * event that is deposited into the EQ.
- *
- * In addition to the struct lnet_handle_eq, the LNet API defines two types
- * associated with events: The ::lnet_event_kind defines the kinds of events
- * that can be stored in an EQ. The struct lnet_event defines a structure that
- * holds the information about with an event.
- *
- * There are five functions for dealing with EQs: LNetEQAlloc() is used to
- * create an EQ and allocate the resources needed, while LNetEQFree()
- * releases these resources and free the EQ. LNetEQGet() retrieves the next
- * event from an EQ, and LNetEQWait() can be used to block a process until
- * an EQ has at least one event. LNetEQPoll() can be used to test or wait
- * on multiple EQs.
