From fd03d8daf417fffbcb27fdb30d60f6c81ed813c8 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Thu, 18 Apr 2013 14:53:15 -0400 Subject: ext4: reserve xattr index for Rich ACL support Jan Kara SUSE is carrying out of tree patches for Rich ACL support for ext4 as they didn't get upstream due to opposition of some VFS maintainers. Reserve xattr index for Rich ACLs so that it cannot be taken by anything else which would force users to backup and reset their Rich ACLs on files.
