[PATCH RFC v2 0/2] can: join filters with per-CPU variables

[Oliver Hartkopp <socketcan@hartkopp.net>]

Hi all,

as Andre Naujoks found some problems in my first patches with multi-threading
I did some investigation how to handle variables to be written inside the
NET_RX softirq without locking. As far as I was able to test this code it works
properly now - even with the multi-thread test from Andre.

If you know how to use per-CPU variables inside NET_RX softirq I would appreciate
your review as I'm not that sure that the per-CPU code is correct. It's my first
time using this technique and is only what I was able to get from other code
examples and available kernel docs.

Many thanks,
Oliver
