From cbaee472f274ea9a98aabe47025f6e5551acadcb Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Fri, 26 Feb 2010 10:54:52 +0800 Subject: ocfs2: Only bug out in direct io write for reflinked extent. In ocfs2_direct_IO_get_blocks, we only need to bug out in case of we are going to write a recounted extent rec. What a silly bug introduced by me!
