Yes, on a quick look it seems that you should be using refcount_t type and not
atomic_t for your reference counter, as you use it as classical refcounter,
i.e.
free the object upon reaching zero, etc:
static void vhba_device_put (struct vhba_device *vdev)
{
if (atomic_dec_and_test(&vdev->refcnt)) {
kfree(vdev);
}
}
Any reason why you didn't use refcount_t type to begin with?
