Hi all, While fuzzing with trinity inside a KVM tools guest running latest -next kernel I've stumbled on the following:
[ 1316.776480] INFO: trying to register non-static key. [ 1316.778981] the code is fine but needs lockdep annotation. [ 1316.780364] turning off the locking correctness validator.
