page-types currently hardcodes /proc/kpageflags as the file to parse. This works when using the tool to examine the state of pageflags on the same system, but does not allow storing a snapshot of pageflags at a given time to debug issues nor on a different system. This allows the user to specify a saved version of kpageflags with a new page-types -F option.

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.
