Message-ID: <1378313423-9sbygyow-mutt-n-horiguchi@ah.jp.nec.com> Date: Wed, 04 Sep 2013 12:50:23 -0400 From: Naoya Horiguchi <n-horiguchi@...jp.nec.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-mm@...ck.org, "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com>, linux-kernel@...r.kernel.org Subject: [PATCH] mm: remove obsolete comments about page table lock The callers of free_pgd_range() and hugetlb_free_pgd_range() don't hold page table locks. The comments seems to be obsolete, so let's remove them.
