Revision 1c59827d1da9bcd6970800d4f8a031b5859e8b4c authored by Hugh Dickins on 20 October 2005, 04:23:43 UTC, committed by Linus Torvalds on 20 October 2005, 06:04:30 UTC
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.
