[DRBD-user] Linux 5.0 type of queue_lock has been changed / drbd module error

[flexoron at gmx.net]

Hello, 

Kernel 5.0.0
File include/linux/blkdev.h

queue_lock is no longer a pointer:

struct request_queue {
:
spinlock_t queue_lock; 
:
}

Kernel 4.20.13
struct request_queue {
spinlock_t *queue_lock; 
}

This triggers a type error/breaks building drbd 9.0.16 module
drbd/drbd_main.c Line 3738
q->queue_lock = &resource->req_lock;

The question is what is wrong: Kernel or DRBD?

To build the module remove address operator:
q->queue_lock = resource->req_lock;

Is this correct?
