Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs: Add missing deinit() call A warning is triggered when repeatedly connecting and disconnecting the rnbd: list_add corruption. prev->next should be next (ffff88800b13e480), but was ffff88801ecd1338. (prev=ffff88801ecd1340).

Fix it by invoking the `deinit()` to appropriately unregister the IB event handler.
