Subject: [PATCH V2 1/3]  mm: Export split_page()
Date: Mon, 18 Mar 2013 13:51:36 -0700	[thread overview]
Message-ID: <1363639898-1615-1-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1363639873-1576-1-git-send-email-kys@microsoft.com>

This symbol would be used in the Hyper-V balloon driver to support 2M
allocations.

In this version of the patch, based on feedback from Michal Hocko
<mhocko@suse.cz>, I have updated the patch description.
