Jason Gunthorpe 1eb9364ce8 IB/uverbs: Fix ordering of ucontext check in ib_uverbs_write ... During disassociation the ucontext will become NULL, however due to how the SRCU locking works the ucontext must only be examined after looking at the ib_dev, which governs the RCU control flow. With the wrong ordering userspace will see EINVAL instead of EIO for a disassociated uverbs FD, which breaks rdma-core.
