Rearrange args for smaller code. lookup revolves around memcmp() which gets len 3rd arg, so propagate length as 3rd arg. readdir and lookup add additional arg to VFS ->readdir and ->lookup, so better add it to the end. Space savings on x86_64: add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-18 (-18) Function old new delta proc_readdir 22 13 -9 proc_lookup 18 9 -9 proc_match() is smaller if not inlined, I promise!

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.
