This patchset converts a number of functions to use folios. This cleans up some khugepaged code and removes a large number of hidden compound_head() calls. --- The first 2 patches break khugepaged max_ptes_shared selftests as the functions now use folio_estimated_sharers() instead of page_mapcount(). This is expected, although I'm uncertain as to whether that's actually a bad thing or not. Some performance testing/feedback would be appreciated on that front.
