When we insert a request, we set the software queue pending bit while holding the software queue lock. However, we clear it outside of the lock, so it's possible that a concurrent insert could reset the bit after we clear it but before we empty the request list. Afterwards, the bit would still be set but the software queue wouldn't have any requests in it, leading us to do a spurious run in the future. This is mostly a benign/theoretical issue, but it makes the following change easier to justify.

README
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.
