_SEGMENT_ENTRY_INVALID denotes the invalid bit in a segment table entry whereas _SEGMENT_ENTRY_EMPTY means that the value of the whole entry is only the invalid bit, as the entry is completely empty. Therefore we use _SEGMENT_ENTRY_INVALID only to check and set the invalid bit with bitwise operations. _SEGMENT_ENTRY_EMPTY is only used to check for (un)equality.

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.
