The series is aimed at getting rid of CURRENT_TIME and CURRENT_TIME_SEC macros.
The macros are not y2038 safe. There is no plan to transition them into being
y2038 safe.
ktime_get_* api's can be used in their place. And, these are y2038 safe.

Thanks to Arnd Bergmann for all the guidance and discussions.

Patches 2-4 were mostly generated using coccinelle scripts.

All filesystem timestamps use current_fs_time() for right granularity as
mentioned in the respective commit texts of patches. This has a changed
signature, renamed to current_time() and moved to the fs/inode.c.

This series also serves as a preparatory series to transition vfs to 64 bit
timestamps as outlined here: https://lkml.org/lkml/2016/2/12/104 .

As per Linus's suggestion in https://lkml.org/lkml/2016/5/24/663 , all the
inode timestamp changes have been squashed into a single patch. Also,
current_time() now is used as a single generic vfs filesystem timestamp api.
It also takes struct inode* as argument instead of struct super_block*.
Posting all patches together in a bigger series so that the big picture is
clear.

As per the suggestion in https://lwn.net/Articles/672598/, CURRENT_TIME macro
bug fixes are being handled in a series separate from transitioning vfs to use.

Changes from v1:
* Change current_fs_time(struct super_block *) to current_time(struct inode *)

* Note that change to add time64_to_tm() is already part of John's
kernel tree: https://lkml.org/lkml/2016/6/17/875 .
