ocfs2: When zero extending, do it by page.
ocfs2_zero_extend() does its zeroing block by block, but it calls a function named ocfs2_write_zero_page(). Let's have ocfs2_write_zero_page() handle the page level. From ocfs2_zero_extend()'s perspective, it is now page-at-a-time. Signed-off-by: Joel Becker <joel.becker@oracle.com> Cc: stable@kernel.org
