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. -- Mel Gorman SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
