| |
Hi,
I'm trying v6.1-rc5 with CONFIG_KMSAN, but the kernel continuously spams "BUG: KMSAN: uninit-value in __init_waitqueue_head".
I tracked it down to lockdep (CONFIG_PROVE_LOCKING=y). The problem goes away if I disable that.
I don't see any obvious use of uninitialized memory in __init_waitqueue_head().
The compiler I'm using is tip-of-tree clang (LLVM commit 4155be339ba80fef).
Is this a known issue?
- Eric
