This is not the root cause. The fix is not good.
This problem is about "INFO: trying to register non-static key. The
code is fine but needs lockdep annotation, or maybe"
This warning is from "lock is not initialized". This is a
use-before-initialized problem.
Right, and it also applies to qp->sq.queue which is set to NULL while do
cleanup
still de-reference it.
The correct fix is to initialize the lock that is complained before it is used.
The thing is it can't be initialized due to error, so I guess you want
to always init them
even for error cases.
