I've hosted my timekeeping tests on github for the last few years:
https://github.com/johnstultz-work/timetests
but I suspect not too many folks have actually used them.
I've been meaning to get them reworked and submitted into the
selftest infrastructure, but haven't had much time until
recently. So I wanted to send this out and get any feedback
to see if they might be able to get into shape for the 4.1
merge window.
I've added both the non-desctructive and destructive tests
(which set the time, possibly to strange values, or tries
to trigger historical issues that could crash the machine).
The destructive tests are run (as root, or with proper
privledge) via:
# make run_destructive_tests
Thoughts or comments here would be greatly appreciated!
thanks!
