The series is aimed at getting rid of CURRENT_TIME, CURRENT_TIME_SEC macros
and replacing current_fs_time() with current_time().
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.
CURRENT_TIME will be deleted after 4.8 rc1 as there is a dependency function
time64_to_tm() for one of the CURRENT_TIME occurance.
Thanks to Arnd Bergmann for all the guidance and discussions.
Patches 3-5 were mostly generated using coccinelle.
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 since v2:
* Fix buildbot error for uninitalized sb in inode.
* Minor fixes according to Arnd's comments.
* Leave out the fnic and deletion of CURRENT_TIME to be submitted after 4.8 rc1.

CURRENT_TIME_SEC is not y2038 safe. current_time() will
be transitioned to use 64 bit time along with vfs in a
separate patch.
There is no plan to transition CURRENT_TIME_SEC to use
y2038 safe time interfaces.
current_time() returns timestamps according to the
granularities set in the inode's super_block.
The granularity check to call current_fs_time() or
CURRENT_TIME_SEC is not required.
Use current_time() directly to update inode timestamp.
Use timespec_trunc during file system creation, before
the first inode is created.
