[PATCH 00/21] Delete CURRENT_TIME and CURRENT_TIME_SEC macros

Deepa Dinamani
2016-06-09T05:04:44Z

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.

All filesystem timestamps use current_fs_time() for the right granularity
as mentioned in the respective commit texts of patches.

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_fs_time() now is used as a single generic filesystem timestamp api.
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 64 bit timestamps.

Some reviewers have requested not to change line wrapping only for the
longer function call names, so checkpatch warnings for such cases are
ignored in the patch series.
