Umm. The problem is the historically the Linux xattr interface was
intended for unstructured data, while some of it is very much structured
and requires interpretation by the VFS and associated entities. So
splitting these out and add proper interface is absolutely the right
thing to do and long overdue (also for other thing like capabilities).
It might make things a little more verbose for LSM, but it fixes a very
real problem.
