And here is v9. Except for typo fixes in comments/description, only 2/7 and 5/7 were changed.
Thanks to everyone for their input. -Eliezer Change log: v9 - correct sysctl proc_handler, reported by Eric Dumazet and Amir Vadai. - more int -> bool changes, reported by Eric Dumazet. - better mask testing in sock_poll(), reported by Eric Dumazet. v8 - split out udp and select/poll into separate patches. what used to be patch 2/5 is now three patches. - type corrections from Amir Vadai and Cong Wang: one unsigned long that was left when changing to cycles_t int -> bool - more detailed patch descriptions. v7 - suggested by Ben Hutchings and Eric Dumazet: type fixes, static for globals in net/core.c, avoid napi_id collisions in napi_hash_add() v6 - many small fixes suggested by Eric Dumazet: data locality, typos, documentation protect napi_hash insert/delete with a spinlock (napi_gen_id is no longer atomic_t since it's only accessed with the spinlock held.) - added IPv6 TCP and UDP support (only minimally tested) v5 - corrections suggested by Ben Hutchings: fixed typos, moved the config option and sysctl value from IPv4 to net - moved sk_mark_ll() to the protocol handlers - removed global id mechanism, replaced with a hashed napi_id. based on code sample from Eric Dumazet Note that ixgbe_free_q_vector() already waits an rcu grace period before freeing the q_vector, so nothing additional needs to be done when adding a call to napi_hash_del(). - simple poll/select support v4 - removed separate config option for TCP as suggested Eric Dumazet. - added linux mib counter for packets received through the low latency path, as suggested by Andi Kleen. - re-allow module unloading, remove module param, use a global generation id instead to prevent the use of a stale napi pointer, as suggested by Eric Dumazet - updated Documentation/networking/ip-sysctl.txt text v3 - coding style changes suggested by Dave Miller v2 - the sysctl knob is now in microseconds. The default value is now 0 (off). - for now the code depends at configure time on CONFIG_I86_TSC - the napi reference in struct skb is now a union with the dma cookie since the former is only used on RX and the latter on TX, as suggested by Eric Dumazet. - we do a better job at honoring non-blocking operations. - removed busy-polling support for tcp_read_sock() - remove dynamic disabling of GRO - coding style fixes - disallow unloading the device module after the feature has been used Credit: Jesse Brandeburg, Arun Chekhov Ilango, Julie Cummings, Alexander Duyck, Eric Geisler, Jason Neighbors, Yadong Li, Mike Polehn, Anil Vasudevan, Don Wood Special thanks for finding bugs in earlier versions: Willem de Bruijn and Andi Kleen ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
