Hmm, have you been able to create test images that have unsorted EA's
in inodes using a standard ext3 kernel implementat?  If so, then this
is a patch which we should push to the distro's since it could cause
data loss, and cause serious malfunctions, especially for people who
have SELinux enabled and are using large inodes for the EA-in-inode
feature....
