The stat shadow saved values rbtree is indexed by a pointer. Fix the comparison function: - We cannot return a pointer delta as an int because that loses bits on 64bit. - Doing pointer arithmetic on the struct pointer only works if the objects are spaced by the multiple of the object size, which is not guaranteed for individual malloc'ed object Replace it with a proper comparison. This fixes various problems with values not being found.

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.
