Sorry, it had no "Singed-off-by", so I assumed it was just for debugging.

Just to be sure, I yesterday built a rc8 kernel with the patch
referenced above and the one that is not yet merged (these two, to be
precise: http://thread.gmane.org/gmane.linux.kernel.mm/90911/focus=91153
http://thread.gmane.org/gmane.linux.kernel.mm/90911/focus=91300
; all the others patches my kswap test kernels contained earlier were
afaics merged a few days ago) and mentioned it in the Fedora bug report.
John gave them a try and  in
https://bugzilla.redhat.com/show_bug.cgi?id=866988#c65 reported "No
problems so far.  I'll check back again in ~24hours."

CU, Thorsten
