Highlights​

Locking fixes to avoid existing and potential deadlocks​

YuniKorn 1.5.0 contained a deadlock as described in YUNIKORN-2521. This deadlock is now fixed along with other potential deadlocks. See YUNIKORN-2544 for a more detailed overview of the locking changes made.

Deadlock detection​

The tool go-deadlock has been integrated to the codebase, which makes it possible to detect potential deadlocks at runtime. Since this slows down the scheduler and increases memory usage, it's disabled by default. However, it's enabled during the unit test phase with "make test". See YUNIKORN-2539 for details.
