[PATCH] hugetlb: fix absurd HugePages_Rsvd
If you truncated an mmap'ed hugetlbfs file, then faulted on the truncated area, /proc/meminfo's HugePages_Rsvd wrapped hugely "negative". Reinstate my preliminary i_size check before attempting to allocate the page (though this only fixes the most obvious case: more work will be needed here).
