Subject: [PATCH 040/354] lockdep: disable self-test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=ecc35b769047b939a39ec23ec401814bbb79e3df
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
