-Subject: [PATCH 6/7] locking/rtmutex: Add a lockdep assert to catch potential
- nested blocking
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
-
-There used to be a BUG_ON(current->pi_blocked_on) in the lock acquisition
-functions, but that vanished in one of the rtmutex overhauls.
-
-Bring it back in form of a lockdep assert to catch code paths which take
-rtmutex based locks with current::pi_blocked_on != NULL.
