Hey Ken. You might want to wait on this for another minute or two. I
will be sending out patches later today to fix up hugetlbfs quotas.
Right now the code does not handle private mappings correctly (ie. it
does not call get_quota() for COW pages and it never calls put_quota()
for any private page). Because of this, your i_blocks number will be
wrong most of the time.
