Cover letter [PATCH 0/4] [UDP]: memory accounting and limitation (take 10)

Hello,

This is the latest patch set of UDP memory accounting and limitation.

To reduce number of atomic access to global variable, the patch set supports per socket accounting using sk_forward_alloc like stream protocols.

My colleagues and I tested the patch set on net-2.6 tree.

Please consider applying.

Changelog take 9 -> take 10:
* supported using sk_forward_alloc
* introduced several memory accounting functions with spin lock
* changed detagram receive functions to be able to customize destructor
* fixed accounting bugs in previous takes

Changelog take 8 -> take 9:
* introduced mem_schdeule functions for datargram protocols
* removed protocol check function, from patch set
* restructured patch set

Changelog take 7 -> take 8:

* sk_datagram_pages(): avoided using divide instruction
* udp_recvmsg(): fixed referring released truesize in accounting

Best regards,
Hideo Aoki
