Hi, This patch adds a netif_release_rx_bufs() function to the netfront driver. It intends to fix the rx buffer page leak. Unfortunaly it doesn't work perfectly, the reason is that reclaiming the pages granted to the backend driver works only if the backend driver gave them back already, filled with network data. Reclaiming unfilled rx buffers does NOT work. I think we need either a way to get back pages with transfer grants without cooperation from the backend driver, or we need some way to say "pretty pretty please, give me back my rx buffers" to the netback driver. comments?
