From 0e090f1e05a563cc9acdda442767176bf1616001 Mon Sep 17 00:00:00 2001 From: Duane Griffin Date: Wed, 7 Jan 2009 18:07:20 -0800 Subject: ext2: don't inherit inappropriate inode flags from parent At present BTREE/INDEX is the only flag that new ext2 inodes do NOT inherit from their parent. In addition prevent the flags DIRTY, ECOMPR, INDEX, IMAGIC and TOPDIR from being inherited. List inheritable flags explicitly to prevent future flags from accidentally being inherited. This fixes the TOPDIR flag inheritance bug reported at http://bugzilla.kernel.org/show_bug.cgi?id=9866.
