Subject: [PATCH 07/34] mn10300: add missing pgtable_page_ctor/dtor calls
Date: Thu, 10 Oct 2013 21:05:32 +0300 [thread overview]
Message-ID: <1381428359-14843-8-git-send-email-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <1381428359-14843-1-git-send-email-kirill.shutemov@linux.intel.com>
It will fix NR_PAGETABLE accounting. It's also required if the arch is
going ever support split ptl.
