As further staging to support processing the HRRQ by other means, access to the HRRQ needs to be serialized by a disabled lock. This will allow safe access in other non-hardware interrupt contexts. In an effort to minimize the period where interrupts are disabled, support is added to queue up commands harvested from the RRQ such that they can be processed with hardware interrupts enabled. While this doesn't offer any improvement with processing on a hardware interrupt it will help when IRQ polling is supported and the command completions can execute on softirq context.

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.
