Date: Tue, 14 May 2013 18:37:28 +0200 From: Lukas Czerner <lczerner@...hat.com> To: linux-mm@...ck.org Cc: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org, linux-ext4@...r.kernel.org, akpm@...ux-foundation.org, hughd@...gle.com, lczerner@...hat.com Subject: [PATCH v4 14/20] ext4: truncate_inode_pages() in orphan cleanup path Currently we do not tell mm to zero out tail of the page before truncate in orphan_cleanup(). This is ok, because the page should not be uptodate, however this may eventually change and I might cause problems. Call truncate_inode_pages() as precautionary measure. Thanks Jan Kara for pointing this out.
