We currently handle a client PROC_DESTROY request by turning it CACHE_NEGATIVE, setting the expired time to now, and then waiting for cache_clean to clean it up later. Since we forgot to set the cache's nextcheck value, that could take up to 30 minutes. Also, though there's probably no real bug in this case, setting CACHE_NEGATIVE directly like this probably isn't a great idea in general. So let's just remove the entry from the cache directly, and move this bit of cache manipulation to a helper function.

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.
