[PATCH 0/4] Make input drivers y2038 safe

by Deepa Dinamani

The series is aimed at making input events y2038 safe. It extends the lifetime of the realtime timestamps in the events to year 2106. The plan is to deprecate realtime timestamps anyway as they are not appropriate for these timestamps as noted in the patch a80b83b7b8 by John Stultz. The series is a result of many discussions with Arnd Bergmann. Deepa Dinamani (4): uinput: Add ioctl for using monotonic/ boot times input: evdev: Replace timeval with timespec64 input: Deprecate real timestamps beyond year 2106 input: serio: Replace timeval by timespec64 drivers/input/evdev.c | 30 +++++++++++-------- drivers/input/input-compat.c | 25 ++++++++-------- drivers/input/input-compat.h | 19 +++++++----- drivers/input/misc/uinput.c | 64 +++++++++++++++++++++++++++++++++++++--- drivers/input/serio/hil_mlc.c | 37 +++++++++++------------ drivers/input/serio/hp_sdc.c | 17 ++++++----- drivers/input/serio/hp_sdc_mlc.c | 10 +++---- include/linux/hil_mlc.h | 6 ++-- include/linux/hp_sdc.h | 6 ++-- include/linux/uinput.h | 3 +- include/uapi/linux/input.h | 37 +++++++++++++++++++++++ include/uapi/linux/uinput.h | 3 ++ 12 files changed, 183 insertions(+), 74 deletions(-) -- 2.7.4

[GIT PULL] [PATCH v4 00/26] Delete CURRENT_TIME and CURRENT_TIME_SEC macros

by Deepa Dinamani

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 . --------------------------------------------------------------- The following changes since commit 09f0834105f7fe315ddaeb77fad15f00565c167e: Add linux-next

[PATCH] md: use seconds granularity for error logging

by Arnd Bergmann

The md code stores the exact time of the last error in the last_read_error variable using a timespec structure. It only ever uses the seconds portion of that though, so we can use a scalar for it. There won't be an overflow in 2038 here, because it already used monotonic time and 32-bit is enough for that, but I've decided to use time64_t for consistency in the conversion.
