In case nvme_rdma_wait_for_cm timeout expires before we get an established or rejected event (rdma_connect succeeded) from rdma_cm, we end up with leaking the ib transport resources for dedicated queue. This scenario can easily reproduced using traffic test during port toggling. Also, in order to protect from parallel ib queue destruction, that may be invoked from different context's, introduce new flag that stands for transport readiness. While we're here, protect also against a situation that we can receive rdma_cm events during ib queue destruction.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
