Subject: [PATCH] lockdep: disable self-test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.8-rt24.tar.xz
The self-test wasn't always 100% accurate for RT. We disabled a few
tests which failed because they had a different semantic for RT. Some
still reported false positives. Now the selftest locks up the system
during boot and it needs to be investigated…

Say Y here if you want the kernel to run a short self-test during
bootup. The self-test checks whether common types of locking bugs
