I pushed this off to Marcelo, he just didn't pull from my
tree yet, which is at:
bk://kernel.bkbits.net/davem/net-2.4
Where you'll find those fixes as:
ChangeSet@1.1498.1.2, 2004-08-18 14:26:09-07:00, davem@nuts.davemloft.net
[IPV4]: Fix theoretical loop on SMP in ip_evictor().
Snapshot the amount of work to do, and just do it.
In this way we avoid a theoretical loop whereby
one cpu sits in ip_evictor() tossing fragments
while another keeps adding a fragment just as we
bring ip_frag_mem down below the low threshold.

ChangeSet@1.1498.1.3, 2004-08-18 14:31:35-07:00, davem@nuts.davemloft.net
[IPV6]: ip6_evictor() has same problem as ip_evictor().
