Kirill A. Shutemov 5cbc198ae0 mm: fix false-positive WARN_ON() in truncate/invalidate for hugetlb ... Hugetlb pages have ->index in size of the huge pages (PMD_SIZE or PUD_SIZE), not in PAGE_SIZE as other types of pages. This means we cannot user page_to_pgoff() to check whether we've got the right page for the radix-tree index. Let's introduce page_to_index() which would return radix-tree index for given page. We will be able to get rid of this once hugetlb will be switched to multi-order entries. Fixes: fc127da085 ("truncate: handle file thp") Link: http://lkml.kernel.org/r/20161123093053.mjbnvn5zwxw5e6lk@black.fi.intel.com Signed-off-by: Kirill A.
