Push clamping timestamps down the call stack into notify_change(), so
in-kernel callers like nfsd and overlayfs will get similar timestamp
set behavior as utimes.

Arnd,
This fixes xfstest generic/402 when run with -overlay setup.
Note that running the test requires latest xfstests with:
acb2ba78 - overlay: support timestamp range check
I had previously posted a fix specific for overlayfs [1],
but Miklos suggested this more generic fix, which should also
serve nfsd and other in-kernel users.
I tested this change with test generic/402 on ext4/xfs/btrfs
and overlayfs, but not with nfsd.
Jeff, could you ack this change is good for nfsd as well?
Thanks,
Amir.

2.17.1
I'm in the process of finishing up the last bits on y2038-unsafe
code in the kernel, this series is for v4l2, which has no problem
with overflow, but has multiple ioctls that break with user space
built against a new 32-bit libc.
I posted similar patches as part of a series back in 2015, the
new version was rewritten from scratch and I double-checked with
the old version to make sure I did not miss anything I had already
taken care of before.
Hans Verkuil worked on a different patch set in 2017, but this
also did not get to the point of being merged.
My new version contains compat-ioctl support, which the old one
did not and should be complete, but given its size likely contains
bugs. I did randconfig build tests, but no runtime test, so
careful review as well as testing would be much appreciated.
With this version, the newly added code takes care of the existing
ABI, while the existing code got moved to the 64-bit time_t
interface and is used internally. This means that testing with
existing binaries should exercise most of the modifications
and if that works and doesn't get shot down in review, we can
probably live without testing the new ABI explicitly.
I'm not entirely happy with the compat-ioctl implementation that
adds quite a bit of code duplication, but I hope this is
acceptable anyway, as a better implementation would likely
require a larger refactoring of the compat-ioctl file, while
my approach simply adds support for the additional data structure
variants.
This is a minor update compared to version 3 of this series,
with bugfixes for small mistakes that I found or that were
reported by automated build bots. I updated the tree at [2]
to this version now.

I've gone through the remaining uses of time_t etc and come up with a
set of 90 patches of varying complexity and importance, to the point
of being able to remove the old time_t/timeval/timespec from the kernel
headers completely.
This set includes the eight patches that I think should be merged
right away and backported into stable kernels if possible.
Please apply individual patches to the respective maintainer trees
for either v5.4 or v5.5 as appropriate.
For reference, the full series of 90 patches can be found at

2.20.0
On compat interfaces, the high order bits of nanoseconds should
be zeroed out. This is because the application code or the libc
do not guarantee zeroing of these. If used without zeroing,
kernel might be at risk of using timespec values incorrectly.
Originally it was handled correctly, but lost during is_compat_syscall()
cleanup. Revert the condition back to check CONFIG_64BIT.

2.24.0
These are updates to devidce drivers and file systems that for some
reason or another were not included in the kernel in the previous
y2038 series.
I've gone through all users of time_t again to make sure the
kernel is in a long-term maintainable state.
Posting these as a series for better organization, but each change
here is applicable standalone.
Please merge, review, ack/nack etc as you see fit. My plan is to
include any patches that don't get a reply this time around in
a future pull request, probably for linux-5.6.
As mentioned before, the full series of 90 patches is available at

This is a series I worked on with Baolin in 2017 and 2018, but we
never quite managed to finish up the last pieces. During the
ALSA developer meetup at ELC-E 2018 in Edinburgh, a decision was
made to go with this approach for keeping best compatibility
with existing source code, and then I failed to follow up by
resending the patches.
Now I have patches for all remaining time_t uses in the kernel,
so it's absolutely time to revisit them. I have done more
review of the patches myself and found a couple of minor issues
that I have fixed up, otherwise the series is still the same as
before.
Conceptually, the idea of these patches is:
- 64-bit applications should see no changes at all, neither
compile-time nor run-time.
- 32-bit code compiled with a 64-bit time_t currently
does not work with ALSA, and requires kernel changes and/or
sound/asound.h changes
- Most 32-bit code using these interfaces will work correctly
on a modified kernel, with or without the uapi header changes.
- 32-bit code using SNDRV_TIMER_IOCTL_TREAD requires the
updated header file for 64-bit time_t support
- 32-bit i386 user space with 64-bit time_t is broken for
SNDRV_PCM_IOCTL_STATUS, SNDRV_RAWMIDI_IOCTL_STATUS and
SNDRV_PCM_IOCTL_SYNC_PTR because of i386 alignment. This is also
addressed by the updated uapi header.
- PCM mmap is currently supported on native x86 kernels
(both 32-bit and 64-bit) but not for compat mode. This series breaks
the 32-bit native mmap support for 32-bit time_t, but instead allows
it for 64-bit time_t on both native and compat kernels. This seems to
be the best trade-off, as mmap support is optional already, and most
32-bit code runs in compat mode anyway.
- I've tried to avoid breaking compilation of 32-bit code
as much as possible. Anything that does break however is likely code
that is already broken on 64-bit time_t and needs source changes to
fix them.
I would like to propose merging this into the alsa tree after
the v5.5 merge window for inclusion into v5.6, to allow a good
amount of testing, in particular for the header changes that
may cause problems for user space applications.
A git branch with the same contents is available for testing at [1].
Please review and test!
