Thanks! I have marked the bug so I can remember to investigate and
forward it to Willy, but if you have time to send your backport before
then to sta...@vger.kernel.org with [2.6.32.y] in the subject line,
cc-ing
Andrea Arcangeli <aarca...@redhat.com>,
x...@kernel.org,
xen-de...@lists.xensource.com,
linux-ker...@vger.kernel.org,
Jan Beulich <jbeul...@suse.com>,
Thomas Gleixner <t...@linutronix.de>,
Ingo Molnar <mi...@elte.hu>,
Rik van Riel <r...@redhat.com>,
Konrad Rzeszutek Wilk <konrad.w...@oracle.com>,
Johannes Weiner <jwei...@redhat.com>,
Jeremy Fitzhardinge <jer...@goop.org>,
Larry Woodman <lwood...@redhat.com>
Peter Zijlstra <pet...@infradead.org>,
Linus Torvalds <torva...@linux-foundation.org>
(or just replying-to-all to the original patch[1] and adding
additional cc lines from the commit message), that would be helpful.
Be sure to mention the upstream commit id, that it is part of 2.6.38
(hence in 3.0.y etc already), your symptoms, and what happened when
you tested the patch.
I imagine Willy will pick it up for the next point release unless
someone objects.
Thanks,
Jonathan
