From: Jan Kara Date: Tue, 12 Nov 2013 23:07:08 +0000 (-0800) Subject: ocfs2: simplify ocfs2_invalidatepage() and ocfs2_releasepage() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=41ecc345984bcc8bf341a3e758c1eb3fc543dd83;p=openwrt%2Fstaging%2Fblogic.git ocfs2: simplify ocfs2_invalidatepage() and ocfs2_releasepage() Ocfs2 doesn't do data journalling. Thus its ->invalidatepage and ->releasepage functions never get called on buffers that have journal heads attached. So just use standard variants of functions from buffer.c.
