Thanks a lot for doing this work! Will take me some time to try it out, but see some questions below... > [1].

How about indication about a test that started to pass since baseline? Tested that started to notrun since baseline?

This is needed to utilize the (relatively) new crash consistency tests (a.k.a. generic/replay) which caught a few nasty bugs. Fun fact: the fix for stable 4.4 almost got missed, because your system was not around ;-) https://marc.info/?l=linux-xfs&m=152852844615666&w=2 I've used a 10GB LOGWRITES_DEV, which seems to be enough for the current tests. I don't think that the dmlogwrite tests play well with external logdev, so we could probably reuse the same device for LOGWRITES_DEV for configs that don't use SCRATCH_LOGDEV.
