v1->v2: add a new patch that introduces get_device_unless_zero() method.
Hello, This patchset introduces get_device_unless_zero() method, Avoid
dev's reference count from 0 to 1, as this will cause bugs in some parts
of the kernel.
We used this method when we fixed an issue with iSCSI delete order.
