◆ num_wqes

unsigned int ib_work_queue::num_wqes

Number of work queue entries.

◆ fill

unsigned int ib_work_queue::fill

Number of occupied work queue entries.

Definition at line 115 of file infiniband.h.

◆ next_idx

unsigned long ib_work_queue::next_idx

Next work queue entry index.

This is the index of the next entry to be filled (i.e. the first empty entry). This value is not bounded by num_wqes; users must logical-AND with (num_wqes-1) to generate an array index.
