Can't help with the secrecy question but the relevant text from the
linked document is copied below.  Looks like its already been removed
from Fedora.

*** SNIPPED TEXT BELOW ***

Environment

-Red Hat Enterprise Linux 6
-kernel-2.6.32-220.2.1.el6

Resolution

-No action necessary.  Red Hat may remove the harmless WARN_ON_ONCE()
call from the kernel in a future kernel errata.

Root Cause
-When a system encounters this issue it will only print the  warning once.
-There are no adverse effects on a system that encounters this  warning.
-This is resolved upstream by removing the WARN_ON_ONCE()  from sched().
