Subject: [ANNOUNCE] rt-tests-2.3

I'm pleased to announce v2.3 of rt-tests

A few things included in this release:

- fixes in cyclicdeadline and deadline_test to prevent double mounting
  of cgroups
- significant clean-ups and fixes to hwlatdetect 
- aarch64 support for oslat
- The addition of the --default-system option in cyclictest
  This runs cyclictest without attempting any tuning. Power management
  is not suppressed so cyclictest measures the system as it is configured.
  This may result in worse realtime behaviour, but is sometimes what you
  are trying to measure.

Thank you to everyone who contributed.

Bug reports, testing, and patches are always appreciated.

You can get this version via git or tarballs as explained below.

Enjoy!
