The fact that we free the async event buffer in nvme_rdma_destroy_admin_queue can cause us to free it more than once because this happens in every reconnect attempt since commit31fdf18401. we rely on the queue state flags DELETING to avoid this for other resources. A more complete fix is to not destroy the admin/io queues unconditionally on every reconnect attempt, but its a bit more extensive and will go in the next release.

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.
