      "message": "[PATCH] v9fs: Documentation, Makefiles, Configuration\n\nOVERVIEW\n\nV9FS is a distributed file system for Linux which provides an\nimplementation of the Plan 9 resource sharing protocol 9P.  It can be\nused to share all sorts of resources: static files, synthetic file servers\n(such as /proc or /sys), devices, and application file servers (such as\nFUSE).\n\nBACKGROUND\n\nPlan 9 (http://plan9.bell-labs.com/plan9) is a research operating\nsystem and associated applications suite developed by the Computing\nScience Research Center of AT\u0026T Bell Laboratories (now a part of\nLucent Technologies), the same group that developed UNIX , C, and C++.\nPlan 9 was initially released in 1993 to universities, and then made\ngenerally available in 1995. Its core operating systems code laid the\nfoundation for the Inferno Operating System released as a product by\nLucent Bell-Labs in 1997. The Inferno venture was the only commercial\nembodiment of Plan 9 and is currently maintained as a product by Vita\nNuova (http://www.vitanuova.com). After updated releases in 2000 and\n2002, Plan 9 was open-sourced under the OSI approved Lucent Public\nLicense in 2003.\n\nThe Plan 9 project was started by Ken Thompson and Rob Pike in 1985.\nTheir intent was to explore potential solutions to some of the\nshortcomings of UNIX in the face of the widespread use of high-speed\nnetworks to connect machines. In UNIX, networking was an afterthought\nand UNIX clusters became little more than a network of stand-alone\nsystems. Plan 9 was designed from first principles as a seamless\ndistributed system with integrated secure network resource sharing.\nApplications and services were architected in such a way as to allow\nfor implicit distribution across a cluster of systems. Configuring an\nenvironment to use remote application components or services in place\nof their local equivalent could be achieved with a few simple command\nline instructions. For the most part, application implementations\noperated independent of the location of their actual resources.\n\nCommercial operating systems haven\u0027t changed much in the 20 years\nsince Plan 9 was conceived. Network and distributed systems support is\nprovided by a patchwork of middle-ware, with an endless number of\npackages supplying pieces of the puzzle. Matters are complicated by\nthe use of different complicated protocols for individual services,\nand separate implementations for kernel and application resources.\nThe V9FS project (http://v9fs.sourceforge.net) is an attempt to bring\nPlan 9\u0027s unified approach to resource sharing to Linux and other\noperating systems via support for the 9P2000 resource sharing\nprotocol.\n\nV9FS HISTORY\n\nV9FS was originally developed by Ron Minnich and Maya Gokhale at Los\nAlamos National Labs (LANL) in 1997.  In November of 2001, Greg Watson\nsetup a SourceForge project as a public repository for the code which\nsupported the Linux 2.4 kernel.\n\nAbout a year ago, I picked up the initial attempt Ron Minnich had\nmade to provide 2.6 support and got the code integrated into a 2.6.5\nkernel.   I then went through a line-for-line re-write attempting to\nclean-up the code while more closely following the Linux Kernel style\nguidelines.  I co-authored a paper with Ron Minnich on the V9FS Linux\nsupport including performance comparisons to NFSv3 using Bonnie and\nPostMark - this paper appeared at the USENIX/FREENIX 2005\nconference in April 2005:\n( http://www.usenix.org/events/usenix05/tech/freenix/hensbergen.html ).\n\nCALL FOR PARTICIPATION/REQUEST FOR COMMENTS\n\nOur 2.6 kernel support is stabilizing and we\u0027d like to begin pursuing\nits integration into the official kernel tree.  We would appreciate any\nreview, comments, critiques, and additions from this community and are\nactively seeking people to join our project and help us produce\nsomething that would be acceptable and useful to the Linux community.\n\nSTATUS\n\nThe code is reasonably stable, although there are no doubt corner cases\nour regression tests haven\u0027t discovered yet.  It is in regular use by several\nof the developers and has been tested on x86 and PowerPC\n(32-bit and 64-bit) in both small and large (LANL cluster) deployments.\nOur current regression tests include fsx, bonnie, and postmark.\n\nIt was our intention to keep things as simple as possible for this\nrelease -- trying to focus on correctness within the core of the\nprotocol support versus a rich set of features.  For example: a more\ncomplete security model and cache layer are in the road map, but\nexcluded from this release.   Additionally, we have removed support for\nmmap operations at Al Viro\u0027s request.\n\nPERFORMANCE\n\nDetailed performance numbers and analysis are included in the FREENIX\npaper, but we show comparable performance to NFSv3 for large file\noperations based on the Bonnie benchmark, and superior performance for\nmany small file operations based on the PostMark benchmark.   Somewhat\npreliminary graphs (from the FREENIX paper) are available\n(http://v9fs.sourceforge.net/perf/index.html).\n\nRESOURCES\n\nThe source code is available in a few different forms:\n\ntarballs: http://v9fs.sf.net\nCVSweb: http://cvs.sourceforge.net/viewcvs.py/v9fs/linux-9p/\nCVS: :pserver:anonymous@cvs.sourceforge.net:/cvsroot/v9fs/linux-9p\nGit: rsync://v9fs.graverobber.org/v9fs (webgit: http://v9fs.graverobber.org)\n9P: tcp!v9fs.graverobber.org!6564\n\nThe user-level server is available from either the Plan 9 distribution\nor from http://v9fs.sf.net\nOther support applications are still being developed, but preliminary\nversion can be downloaded from sourceforge.\n\nDocumentation on the protocol has historically been the Plan 9 Man\npages (http://plan9.bell-labs.com/sys/man/5/INDEX.html), but there is\nan effort under way to write a more complete Internet-Draft style\nspecification (http://v9fs.sf.net/rfc).\n\nThere are a couple of mailing lists supporting v9fs, but the most used\nis v9fs-developer@lists.sourceforge.net -- please direct/cc your\ncomments there so the other v9fs contibutors can participate in the\nconversation.  There is also an IRC channel: irc://freenode.net/#v9fs\n\nThis part of the patch contains Documentation, Makefiles, and configuration\nfile changes.\n\nSigned-off-by: Eric Van Hensbergen \u003cericvh@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
