mm: Fix filemap_invalidate_inode() to use invalidate_inode_pages2_range()
Fix filemap_invalidate_inode() to use invalidate_inode_pages2_range()
rather than truncate_inode_pages_range(). The latter clears the
invalidated bit of a partial pages rather than discarding it entirely.
This causes copy_file_range() to fail on cifs because the partial pages at
either end of the destination range aren't evicted and reread, but rather
just partly cleared.
This causes generic/075 and generic/112 xfstests to fail.
Fixes: 74e797d79cf1 ("mm: Provide a means of invalidation without using launder_folio")
