You seem to need the handler mostly for getting back to the prefix
from the handler. This is a pretty clear indicator that you don't
want to use the xattr_handler splitting but deal with the whole
attr name. Take a look at the btrfs code after my recent xattr changes
on how to handle this more nicely.

Tao, Can you look into this?

I have looked the patch for btrfs about this. We are different.
Btrfs store the whole xattr name including the prefix "user." "trusted.", we store index number instead of it.
