Comment 12 Josh Bressers 2011-03-08 18:10:51 UTC 
This issue only affects Red Hat Enterprise Linux 6. We did not properly backport upstream commit b48fa6b9. So we needed additional patch that fixes the improper backport.
Comment 13 Petr Matousek 2011-03-08 19:34:59 UTC 
Statement:

This issue only affects Red Hat Enterprise Linux 6 as we did not properly backport upstream commit b48fa6b9. The versions of the Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, and Red Hat Enterprise MRG are not affected.
