Merge branch 'vfs_timespec64' of https://github.com/deepa-hub/vfs into vfs-timespec64
Pull the timespec64 conversion from Deepa Dinamani: "The series aims to switch vfs timestamps to use struct timespec64. Currently vfs uses struct timespec, which is not y2038 safe. The flag patch applies cleanly. I've not seen the timestamps update logic change often. The series applies cleanly on 4.17-rc6 and linux-next tip (top commit: next-20180517). I'm not sure how to merge this kind of a series with a flag patch. We are targeting 4.18 for this. Let me know if you have other suggestions. The series involves the following: 1. Add vfs helper functions for supporting struct timepec64 timestamps. 2. Cast prints of vfs timestamps to avoid warnings after the switch. 3. Simplify code using vfs timestamps so that the actual replacement becomes easy. 4. Convert vfs timestamps to use struct timespec64 using a script. This is a flag day patch. I've tried to keep the conversions with the script simple, to aid in the reviews. I've kept all the internal filesystem data structures and function signatures the same. Next steps: 1. Convert APIs that can handle timespec64, instead of converting timestamps at the boundaries. 2. Update internal data structures to avoid timestamp conversions." I've pulled it into a branch based on top of the NFS changes that are now in mainline, so I could resolve the non-obvious conflict between the two while merging.
