Thanks Greg. Linus's tree now contains my fix 5aae9265ee1a ("mm: prep_compound_tail() clear page->private") to Mel's fix 71e2d666ef85 ("mm/huge_memory: do not clobber swp_entry_t during THP split") so they can now go on together into 6.0 stable. They would also have been good in 5.19 stable: but too late now, it's EOL. Hugh
