patch to resolve the deadlock
This is the rhel5 version of this patch, I tested it with the reproducer given to me by fujitsu and it resolves the problem.
in kernel-2.6.18-110.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Updating PM score. Removed 439548 from the depends on field as it causes problems with the R5.4 prioritized kernel list query. Nacking 5.3.z proposal. The patchset consists of 24 individual patchset and it is too intrusive to pull it into 5.3.z. If still confident about 5.3.z needs, please contact Linda Wang to clarify.
