These two patches were replaced by the better one from Benjamin, and it has been
merged into upstream.
commit fa8a53c39f3fdde98c9eace6a9b412143f0f6ed6
Author: Benjamin LaHaise <bcrl@kvack.org>
Date: Fri Mar 28 10:14:45 2014 -0400
aio: v4 ensure access to ctx->ring_pages is correctly serialised for migration
And I have already received the notify that it has been applied into stable tree.

Gu
