Subject: Re: [RFC] Page table sharing
Date: Fri, 22 Feb 2002 07:32:31 +0100	[thread overview]
Message-ID: <E16e9Fw-0005I3-00@starship.berlin> (raw)
In-Reply-To: <Pine.LNX.4.33.0202181758260.24597-100000@home.transmeta.com> <E16e8Gf-0005HN-00@starship.berlin>
In-Reply-To: <E16e8Gf-0005HN-00@starship.berlin>

The following gross mistake was noticed promptly by Rik van Riel:

	spin_lock(&page_table_share_lock);
-       if (page_count(virt_to_page(pte)) == 1) {
+	if (put_page_testzero(virt_to_page(pte))) {
		pmd_clear(dir);
		pte_free_slow(pte);
	}
	spin_unlock(&page_table_share_lock);

However, oddly enough, that's not the memory leak.
