TOMOYO Linux needs method for calculating pathname in LSM module.
However, we have received comment from Al Viro, the vfs maintainer,
that adding vfsmount parameter to vfs helper functions (and LSM hooks)
is not preferable. We have asked some people (including Al), and we
came back to the most straightforward approach; adding new LSM hooks
where vfsmount is available.
The attached patch introduces several new LSM hooks TOMOYO Linux
needs. It has less impact to existing LSM module and no impact to vfs
helper functions. Please review it.

As always, the community will be eager to see the code that makes
use of these hooks.
you can bet that if these hooks are accepted, AppArmor and the various
other LSMs that have not been accepted becouse of the problems they have
dealing with paths will switch to using the 'approved' hooks.
so there are several bodies of code that have already been published that
would want to use hooks like these if they are available.
