When the driver is unloading, the nvme transport could be in the process of submitting new requests, will send abort requests to terminate associations, or may make LS-related requests. The driver's abort and request entry points currently is ignorant of the unloading state and is starting the requests even though the infrastructure to complete them continues to teardown. Change the entry points for new requests to check whether unloading and if so, reject the requests. Abort routines check unloading, and if so, noop the request. An abort is noop'd as the teardown paths are already aborting/terminating the io outstanding at the time the teardown initiated.

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.
