This breaks the build for me.
$ make -skj"$(nproc)" ARCH=x86_64 LLVM=1 mrproper defconfig kernel/locking/rtmutex_api.o kernel/locking/rtmutex_api.c:93:1: error: expecting rt_mutex 'lock' to be held at the end of function [-Werror,-Wthread-safety-analysis] 93 | } | ^ kernel/locking/rtmutex_api.c:90:14: note: rt_mutex acquired here 90 | void __sched rt_mutex_lock(struct rt_mutex *lock) | ^ 1 error generated.
This is with LLVM 22.1.5, in case it matters.
Cheers, Nathan
