The patch titled
ext2: don't inherit inappropriate inode flags from parent
has been removed from the -mm tree. Its filename was
ext2-dont-inherit-inappropriate-inode-flags-from-parent.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: ext2: don't inherit inappropriate inode flags from parent
From: "Duane Griffin" <duaneg@xxxxxxxxx>
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.
