Hello,
I will test this but can only do so on Friday.
On 3.0.9-rt25 (which I have been using here) patch 30765b92 is already
applied. And it is also present in patch-3.0.10-rt27.patch.
So the original patch from Peter
(http://article.gmane.org/gmane.linux.kernel.mm/70863/match=) applies
cleanly here.
Regards,
Thomas
