Don't show nr_indirectly_reclaimable in /proc/vmstat,
because there is no need in exporting this vm counter
to the userspace, and some changes are expected
in reclaimable object accounting, which can alter
this counter.

I don't think it should be a per-node vmstat, in this case.  It appears 
only to be used for the global context.  Shouldn't this be handled like 
totalram_pages, total_swap_pages, totalreserve_pages, etc?

Hi, David!

I don't see any reasons why re-using existing infrastructure for
fast vm counters is bad, and why should we re-invent it for this case.

Because now you have to modify the existing infrastructure for something 
that shouldn't be a vmstat in the first place?
