There's a patch from David Howells which makes the ability to make a
session keyring from a kernel module, I guess it never got into shipping
kernels.
the drawback to this, is that you need the keyutils library (and any
program using setpag() will need to link with the keyutils as well).
Which is precisely why I hadn't finished this, I was trying like the
