From bce997682fe3121516f5a20cf7bad2e6029ba018 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Mon, 18 Jun 2007 11:12:36 -0700 Subject: ocfs2: harden buffer check during mapping of page blocks We don't want to submit buffer_new blocks for read i/o. This actually won't happen right now because those requests during an allocating write are all nicely aligned. It's probably a good idea to provide an explicit check though.
