Subject: [PATCH 0/2] kselftests: set-timer-lat: test one-shot timers

This patchset expands set-timer-lat to cover one-shot timers.  This is
inspired by a recent regression in the -stable tree, which caused one-shot
alarm timers to repeat at a 1 ns interval.

The first patch adjusts how early-firing timers are reported, so faulty
kernels won't cause the test to spam the console with failure messages.
The second patch actually adds the one-shot testcases.

Greg Hackmann (2):
  kselftests: set-timer-lat: tweak reporting when timer fires early
  kselftests: set-timer-lat: add one-shot timer test cases
