[PATCH] mm: hugetlb truncation fixes
hugetlbfs allows truncation of its files (should it?), but hugetlb.c often
forgets that: crashes and misaccounting ensue.
copy_hugetlb_page_range better grab the src page_table_lock since we don't
want to guess what happens if concurrently truncated. unmap_hugepage_range
rss accounting must not assume the full range was mapped. follow_hugetlb_page
must guard with page_table_lock and be prepared to exit early.
Restyle copy_hugetlb_page_range with a for loop like the others there.
