Changes in v4: - Introduce vhost_scsi_inflight - Drop array to track flush Changes in v3: - Rebase - Drop 'tcm_vhost: Wait for pending requests in vhost_scsi_clear_endpoint()' in this series, we already did that in 'tcm_vhost: Use vq->private_data to indicate

Below should be useful for some experiments Jason is doing. I thought I'd send it out for early review/feedback. Compiled-only at this point. event idx feature allows us to defer interrupts until a specific # of descriptors were used. Sometimes it might be useful to get an interrupt after a specific descriptor, regardless. This adds a descriptor flag for this, and an API to create an urgent
