Subject: CLOCK_MONOTONIC, BOOTTIME, suspend and screensaver regression

Hi!

In 4.17-rc1 I have weird problems with network manager... and I also
have screensaver kicking just after resume.

Searching the git logs:

       - The most interesting change is the consolidation of clock
         MONOTONIC
	          and clock BOOTTIME.

         Clock MONOTONIC behaves now exactly like clock BOOTTIME and
         does
	          not longer ignore the time spent in suspend. A new
         clock
	          MONOTONIC_ACTIVE is provived which behaves like
         clock MONOTONIC in
	          kernels before this change. This allows applications
         to
	          programmatically check for the clock MONOTONIC
         behaviour.

         As discussed in the review thread, this has the potential of
	          breaking user space and we might have to revert
	          this. Knock on wood
		           that we can avoid that exercise.


...I believe you are breaking userspace for me. How can we check that?
