Subject: [GIT PULL] [PATCH v4 00/26] Delete CURRENT_TIME and CURRENT_TIME_SEC macros
Date: Sat, 13 Aug 2016 15:48:12 -0700 [thread overview]
Message-ID: <1471128518-24075-1-git-send-email-deepa.kernel@gmail.com> (raw)
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 64 bit timestamps.
Changes from v3:
* Rebased to 4.8-rc1 to avoid merge conflicts.
* Added CURRENT_TIME deletion and fnic patches back as time64_to_tm() is merged.
* Rearranged a couple of instances of CURRENT_TIME.
Changes from v2:
* Fix buildbot error for uninitialized 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.
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 .
