Cover letter [RFC/PATCH 0/3] UDP memory usage accounting(take 2)
This patch set try to introduce memory usage accounting for
UDP(currently ipv4 only).
3 points are improved along with some feedback.
(a) to improve scalability, avoiding atomic_*()s as small as
possible
(b) avoiding UDP specific code in IP layer
(c) supporting socket destruction accounting
To implement (b), there is a side effect which affects
accounting on TCP socket. If you find the good solution
to avoid this side effect, please let me know.
Unfortunately, I don't have any NIC with UFO.
So this patch set is not tested with UFO supported
device.
This patch set is for 2.6.23-rc8.
I appreciate your comment/test/feedback.
