hi I've some problems with netback 1.what's mmap_pages for, which come from balloon operation ？ mmap_pages = alloc_empty_pages_and_pagevec(MAX_PENDING_REQS) 2.what's the meaning of "refcnt" defined in netif_t (netif->refcnt) 3.irq enable and disable such as disable_irq(netif->irq); why netback use such enable & disable operations while netfront dont use for its irq? 4.blank "resume" operation for netback why netfront has "resueme" defined, while not in netback? which event will result in calling the "resume" function? thanks in advance!
