From: Jiri Pirko <[email protected]> Implement an empty disassociate_ucontext() callback so the RDMA core can move rxe devices between net namespaces. The core requires this callback to reset user contexts without waiting for userspace.
rxe needs no teardown here: its user-mapped queues live in reference-counted vmalloc memory (see rxe_mmap.c) that stays valid while userspace holds the mappings.
