Description IBM Bug Proxy 2007-04-17 21:55:58 UTC

This patch: http://lkml.org/lkml/2006/11/17/305 tried to fix some problems with
posix cpu timers during 2.6.19, but in the process created a new bug. The
problem was then fixed by this patch: http://lkml.org/lkml/2007/2/21/478 during
2.6.21. We need this patch for posix cpu timers to function correctly. In case
RHEL5-RT gets rebased to 2.6.21, we will get this patch automatically, but in
case that doesn't happen, this patch needs to be backported to the RHEL5-RT
kernel. The patch is a simple one-line fix that appears to be quite safe to
backport.

I have raised this bug so that this problem doesn't get slipped between our
fingers.

I have tested kernel-rt-2.6.21-2.el5rt pulled down from Clark William's page and
confirmed that this problem is fixed in that kernel.
