Presumably this would include moving all of the filesystems to use
inode->i_ino instead of their own private file ID number, e.g. the NFS
issue pointed out in the original patch?  If not, I think most of us
in the LSM/audit space still have a need for a filesystem agnostic way
to determine the inode number from an inode struct.
