ext4: fix mmap data corruption when blocksize < pagesize

Browse source

commit d6320cbfc9 upstream.

Use truncate_isize_extended() when hole is being created in a file so that
->page_mkwrite() will get called for the partial tail page if it is
mmaped (see the first patch in the series for details).
