[PATCH v3 08/11] vdpa: Add eventfd for the vdpa callback
...t to do more tweaks to mention:
1) irq_ctx is optional
2) that when the irq_ctx is set, the vDPA driver must guarantee that
signaling it is functional equivalent to triggering the callback. When
set, vDPA parent can signal it directly instead of triggering the callback.

There's no IRQ concept at the virtual vDPA bus level, so it's probably
better to rename it as "trigger".
Btw, should we select EVENTFD for vDPA?
Thanks
