I'm not reviewing this series, I just heard it mentioned at LSF/MM and again on a DAX thread and am taking a quick glance out of curiousity. FWIW, I saw the lockup-on-umount warning every time I ran Dave's xfsrepair workload when unmounting after running fsmark. I didn't report it because Dave mentioned at Vault that it was a known problem and someone was looking at it already.
