The driver had been abusing the cq_vector state to know if new submissions were safe, but that was before we could quiesce blk-mq. If the controller happens to get an interrupt through while we're suspending those queues, 'no irq handler' warnings may occur. This patch will disable the interrupts only after the queues are deleted.

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.
