Statement

This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4 as they did not provide support for FUSE. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 5 as they did not backport the upstream commit 3b463ae0c6264f that introduced this issue.
