I agree with the first 3 patches, but not the last one.
Changing the API just for a performance hack is not necessary. Instead make
the algorithm smarter and use per-cpu values.

Thanks for the feedback, I would very much prefer any of the other two approaches
I tried (per-cpu pool and per-cpu for each fdb), from the two the second one -
per-cpu for each fdb is much simpler, so would it be acceptable to do per-cpu allocation
for each fdb ?

Okay, after some more testing the version with per-cpu per-fdb allocations, at 300 000 fdb entries
I got 120 failed per-cpu allocs which seems okay. I'll wait a little more and will repost the series
with per-cpu allocations and without the RFC tag.

Thanks,
 Nik
