Statement

This issue did not affect the Linux kernels as shipped with Red Hat Enterprise Linux 4, 6, and Red Hat Enterprise MRG, as they either do not have the sample_to_timespec() function, or have already backported upstream commit f8bd2258, which addresses this issue. It was addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2011-1386.html.
