Introduction
This patch series is aimed at getting rid of CURRENT_TIME and CURRENT_TIME_SEC
macros.
The idea for the series evolved from my discussions with Arnd Bergmann.
This was originally part of the RFC series[2]:
https://lkml.org/lkml/2016/1/7/20 (under discussion).
Dave Chinner suggested moving bug fixes out of the feature series to keep the
original series simple.
There are 354 occurrences of the the above macros in the kernel.
The series will be divided into 4 or 5 parts to keep the parts manageable
and so that each part could be reviewed and merged independently.
This is part 2 of the series.
Motivation
The macros: CURRENT_TIME and CURRENT_TIME_SEC are primarily used for
filesystem timestamps.
But, they are not accurate as they do not perform clamping according to
filesystem timestamps ranges, nor do they truncate the nanoseconds value
to the granularity as required by the filesystem.
The series is also viewed as an ancillary to another upcoming series[2]
that attempts to transition file system timestamps to use 64 bit time to
make these y2038 safe.
There will also be another series[3] to add range checks and clamping to
filesystem time functions that are meant to substitute the above macros.
Solution
CURRENT_TIME macro has an equivalent function:
struct timespec current_fs_time(struct super_block *sb)
These will be the changes to the above function:
1. Function will return the type y2038 safe timespec64 in [2].
2. Function will use y2038 safe 64 bit functions in [2].
3. Function will be extended to perform range checks in [3].
A new function will be added to substitute for CURRENT_TIME_SEC macro
in the current series:
struct timespec current_fs_time_sec(struct super_block *sb)
These will be the changes to the above function:
1. Function will return the type y2038 safe timespec64 in [2].
2. Function will use y2038 safe 64 bit functions in [2].
3. Function will be extended to perform range checks in [3].
Any use of these macros outside of filesystem timestamps will
be replaced by function calls to appropriate time functions.

CURRENT_TIME macro is not appropriate for filesystems as it
doesn't use the right granularity for filesystem timestamps.
Use current_fs_time() instead.

This is in preparation for the series that transitions
filesystem timestamps to use 64 bit time and hence make
them y2038 safe.
CURRENT_TIME macro will be deleted before merging the
aforementioned series.
Use current_fs_time() instead of CURRENT_TIME for inode
timestamps.
struct kernfs_node is associated with a sysfs file/ directory.
Truncate the values to appropriate time granularity when
writing to inode timestamps of the files.
ktime_get_real_ts() is used to obtain times for
struct kernfs_iattrs. Since these times are later assigned to
inode times using timespec_truncate() for all filesystem based
operations, we can save the supers list traversal time here by
using ktime_get_real_ts() directly.

CURRENT_TIME macro is not appropriate for filesystems as it
doesn't use the right granularity for filesystem timestamps.
Use current_fs_time() instead.

Why would we care? This is a pseudo-fs. There is no expectation w.r.t.
timestamp accuracy or resolution.

CURRENT_TIME is not y2038 safe.
We are switching all vfs timestamps to use 64 bit time.
And, deleting all references to CURRENT_TIME.
So CURRENT_TIME users will be replaced by either ktime_get_* apis
or current_fs_time_* apis.
There is going to be another series (based on
https://lkml.org/lkml/2016/2/12/76)
which switches vfs time to 64 bit.
This means [a,c,m] times in struct inode, struct attr and struct kstat
will be changed to use timespec64.
Even though this is a psuedo-fs, we choose to use filesystem apis
rather than ktime_get_* apis as current_fs_time_* apis will switch time
data types together with vfs.

As Deepa said, the primary goal is to unify the interface, so we have only
one place function that handles setting the time in an inode, and we want
to avoid CURRENT_TIME, as that is currently used in a couple of places
for things other than inode timestamps that we don't want to convert to
64-bit times at the same time.
current_fs_time() has a very small overhead compared to CURRENT_TIME,
if you think it's worth avoiding that, we could introduce a
current_pseudo_fs_time() function that does not take a superblock
argument but is more tied to inode timestamps than CURRENT_TIME is.
