I'm in favour of just removing it.  2.4-ac went through a phase
of reporting tmpfs' shmem_nrpages (in kB) there; but it was an
entirely different meaning for MemShared, needs the releasepage
infrastructure of 2.4-ac for proper accounting (which I've never
cared to ask for in mainline); and 2.4.20-ac always says 0 like
everyone else.
