Comment 1 Bill Nottingham 2008-10-02 20:23:18 UTC

RHEL 6 will include a newer kernel than 2.6.26, so this should not be a problem.

The feature requested has already been accepted into the upstream code base
planned for the next major release of Red Hat Enterprise Linux.

When the next milestone release of Red Hat Enterprise Linux 6 is available,
please verify that the feature requested is present and functioning as
desired.

Comment 2 Hans-Joachim Picht 2009-09-22 20:53:04 UTC

Code is included in the rhel6 kernel via upstream. Marked as
CLOSED/CURRENTRELEASE by  Hans-Joachim Picht <hpicht>
