Only the briefest of testing, but mmotm 2022-03-06-20-33 minus mm-thp-dont-have-to-lock-page-anymore-when-splitting-pmd.patch plus mm-huge_memory-remove-stale-locking-logic-from-__split_huge_pmd.patch plus mm-huge_memory-remove-stale-locking-logic-from-__split_huge_pmd-fix.patch is infinitely better than mmotm 2022-03-06-20-33. I could just about reach a login on yesterday's mmotm, but graphics no. Couldn't spend time to investigate, but Naresh's mail today that LTP thp04 timeouted (hey, I'm English, we say timed out!) inspired me to try booting with transparent_hugepage=never on cmdline, and that worked. Again, no time to investigate, but the combination above has booted and is running load, including transparent hugepages. And before setting that load going, I did try LTP thp04, which passed. (There is an unrelated console printk lockdep spew, and am I the only one to see these mm/workingset.c:567 shadow_lru_isolate warnings that started up a week or three ago?) Must dash, Hugh
