From 27d2e1491985e95c486d991302e399f5c584b4eb Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Sun, 14 Jun 2009 17:23:09 +0300 Subject: exofs: Remove IBM copyrights Boaz, Congrats on getting all the OSD stuff into 2.6.30! I just pulled the git, and saw that the IBM copyrights are still there. Please remove them from all files: * Copyright (C) 2005, 2006 * International Business Machines IBM has revoked all rights on the code - they gave it to me. Thanks!

Open code just the parts that are currently needed. TODO: Farther optimization can be done to sync the sb only on inode update of new files, Usually the sb update is not needed in exofs.
