This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not backport the upstream commit 5dee9e7c that introduced this issue. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-1189.html, and https://rhn.redhat.com/errata/RHSA-2011-1253.html.
