Subject: [RFC][PATCH 1/3] pass mm in to pgtable ctor/dtor
Date: Fri, 15 Apr 2011 10:38:22 -0700 [thread overview]
Message-ID: <20110415173822.40111D3F@kernel> (raw)
In-Reply-To: <20110415173821.62660715@kernel>
The pagetable page constructor and destructor functions are
handy places to hook in our new accounting. But, if we are
going to store the accounting in the mm, we need the mm
passed in to these functions as well.
