The patch below is sufficient to unbreak blktests. I think that the deadlock while unloading rdma_rxe happens because the RDMA core waits for all ib_dev references to be dropped before dealloc_driver is called.
Which is required, yes
The rdma_rxe dealloc_driver implementation drops an ib_dev reference.
Where does it do that? I didn't notice it? Jason
