...thread_should_stop(). 4. Use __get_free_pages() to replace kzalloc(). 5. Modify the changes to netif_be_dbg(). 6. Use MODPARM_netback_kthread to determine whether using tasklet or kernel thread. 7. Put small fields in the front, and large arrays in the end of struct xen_netbk. 8. Add more checks in netif_page_release(). Current netback uses one pair of tasklets for Tx/Rx data transaction. Netback tasklet could only run at one CPU at a time, and it is used to serve all the netfronts. Therefore it has become a performance bottle neck. This patch is to use multiple tasklet pairs to replace the current single pair...

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it
