This is the RHEL4 version of this bug.

+++ This bug was initially created as a clone of Bug #235648 +++

for function nlm_lookup_host in fs/lockd/host.c,
when the host found is not the head in the bucket in the hash table, it will be
moved to head. source is like this,
---------------------
  if (hp != nlm_hosts + hash) {
                                *hp = host->h_next;
                                host->h_next = nlm_hosts[hash];
                                nlm_hosts[hash] = host;
                        }
--------------------------
won't it lose hosts that are originally between the one to search for and the
original head? for *hp is not handled after *hp = host->h_next;

this problem covers rhel4 and rhel5.  
i think it fixed in kernel 2.6.20.
