UBUNTU: ubuntu: overlayfs -- inode_only_permission: export inode level permissions checks
We need to be able to check inode permissions (but not filesystem implied
permissions) for stackable filesystems. Now that permissions involve
checking with the security LSM, cgroups and basic inode permissions it is
easy to miss a key permission check and introduce a security vunerability.
Expose a new interface for these checks.
