Re: [GIT PULL] vfs: Add support for timestamp limits

[Mike Marshall <hubcap@omnibond.com>]

Hi Deepa...

I installed this patch series on top of Linux 5.3-rc6 and ran xfstests
on orangefs and got a regression... generic/258 failed
with: "Timestamp wrapped"...

# cat results/generic/258.out.bad
QA output created by 258
Creating file with timestamp of Jan 1, 1960
Testing for negative seconds since epoch
Timestamp wrapped: 0
Timestamp wrapped
(see /home/hubcap/xfstests-dev/results//generic/258.full for details)

Just to double check, I compiled Linux 5.3-rc6 without the timestamp series,
and 258 passed... then added the patch series back and the failure returned...

Also.... when I was using "git am" to apply the patch series, the ceph patch
failed, so I "git skipped" it...

I obtained the patch series from: https://github.com/deepa-hub/vfs limits
today.
