Mm Tree
Among Linux kernel developers, the -mm tree refers to a version of the kernel source code maintained by Andrew Morton. The -mm kernel tree used to fill the role of Linux kernel development builds, formerly identified by odd version numbers following "2.6." (see this section on Linux kernel version numbering). New and experimental code used to find its way into a 2.6.x-mm kernel build. Historically, the -mm tree focused on new developments for the memory management part of the kernel (mm). Occasionally, the -mm tree was overloaded with new patches, so testing it became difficult. On September 17, 2007, Morton sent a mail saying that "this just isn't working any more". The presence of the new linux-next git repository has offloaded much of the work that made mm maintenance troublesome, allowing Morton to continue to use quilt A quilt is a multi-layered textile, traditionally composed of two or more layers of fabric or fiber. Commonly three layers are used with a filler ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Kernel
The Linux kernel is a free and open-source, monolithic, modular, multitasking, Unix-like operating system kernel. It was originally authored in 1991 by Linus Torvalds for his i386-based PC, and it was soon adopted as the kernel for the GNU operating system, which was written to be a free (libre) replacement for Unix. Linux is provided under the GNU General Public License version 2 only, but it contains files under other compatible licenses. Since the late 1990s, it has been included as part of a large number of operating system distributions, many of which are commonly also called Linux. Linux is deployed on a wide variety of computing systems, such as embedded devices, mobile devices (including its use in the Android operating system), personal computers, servers, mainframes, and supercomputers. It can be tailored for specific architectures and for several usage scenarios using a family of simple commands (that is, without the need of manually editing its source code ...

Source Code
In computing, source code, or simply code, is any collection of code, with or without comments, written using a human-readable programming language, usually as plain text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by an assembler or compiler into binary machine code that can be executed by the computer. The machine code is then available for execution at a later time. Most application software is distributed in a form that includes only executable files. If the source code were included it would be useful to a user, programmer or a system administrator, any of whom might wish to study or modify the program. Alternatively, depending on the technology being used, source code may be interpreted and executed directly. Definitions Richard Stallman's definition, formulated in his 1989 seminal li ...

Andrew Morton (computer Programmer)
Andrew Keith Paul Morton (born 1959) is an Australian software engineer, best known as one of the lead developers of the Linux kernel. He is currently a co-maintainer of the Ext3 file system, the journaling layer for block devices (JBD) and Memory Management. In the late 1980s, he was one of the partners of a company in Sydney, Australia that produced a kit computer called the Applix 1616, as well as a hardware engineer for the (now-defunct) Australian gaming equipment manufacturer Keno Computer Systems. He holds an honours degree in electrical engineering from the University of New South Wales in Australia. Morton maintains a Linux kernel patchset known as the ''mm'' tree, which contains work-in-progress patches that might later be accepted into the official Linux tree maintained by Linus Torvalds. "mm" as a primary testing ground became unmanageably large and busy, and in 2008 the "linux-next" tree was created to fill much of this role. In 2001, Andrew Morton and his famil ...

Quilt (software)
Quilt is a software utility for managing a series of changes to the source code of any computer program. Such changes are often referred to as " patches" or "patch sets". Quilt can take an arbitrary number of patches as input and condense them into a single patch. In doing so, Quilt makes it easier for many programmers to test and evaluate the different changes amongst patches before they are permanently applied to the source code. Tools of this type are very important for distributed software development, in which many programmers collaborate to test and build a single large codebase. For example, quilt is heavily used by the maintainers of the Linux kernel. Quilt evolved from a set of patch-management scripts originally written by Linux kernel developer Andrew Morton, and was developed by Andreas Grünbacher for maintaining Linux kernel customizations for SuSE Linux. It is now being developed as a community effort, hosted at the GNU Savannah project repository and distr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
