2.4 has the same problem. Before I post the patch, 2.4 seems to be
missing this patch, do you already have it queued or should I send
a 2.4 version first ?

 [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.
