Hi all, This is a roll-up of a few fixes[1] for reverse-mapping in 4.8. The patches have been xfstested with the 'auto' group on x64 and (afaict) don't cause any regressions. This is an extraordinary way to eat your data. Enjoy! Comments and questions are, as always, welcome. --D [1] https://github.com/djwong/linux/tree/for-dave-for-4.8-6
