The series is aimed at adding timestamp checking and policy related to it to vfs.
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.
We're going to need regression tests for this to ensure that it works properly and that we don't inadvertantly break it in future. Can you write some xfstests that exercise this functionality and validate that the mount behaviour, clamping and range limiting is working as intended?
Cheers,
Dave.
