The series was developed with discussions and guidance from Arnd Bergmann. The original idea for the series was the discussion: https://lkml.org/lkml/2014/5/30/551 Patches 5 and 6 can be merged only after vfs is transitioned to use 64 bit timestamps as noted in the respective commit texts. The series only includes adding range limits to filesystems: ext4 and afs as examples to keep the series simple. Every filesystem will be updated to add these limits. There is an ext4 current_time() api replacement patch that the series depends on: https://lkml.org/lkml/2016/6/9/38 . This needs reposting to the mailing list.
