^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   3) ReiserFS is hereby licensed under the GNU General
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   4) Public License version 2.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   6) Source code files that contain the phrase "licensing governed by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   7) reiserfs/README" are "governed files" throughout this file.  Governed
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   8) files are licensed under the GPL.  The portions of them owned by Hans
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   9) Reiser, or authorized to be licensed by him, have been in the past,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  10) and likely will be in the future, licensed to other parties under
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  11) other licenses.  If you add your code to governed files, and don't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  12) want it to be owned by Hans Reiser, put your copyright label on that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  13) code so the poor blight and his customers can keep things straight.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  14) All portions of governed files not labeled otherwise are owned by Hans
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  15) Reiser, and by adding your code to it, widely distributing it to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  16) others or sending us a patch, and leaving the sentence in stating that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  17) licensing is governed by the statement in this file, you accept this.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  18) It will be a kindness if you identify whether Hans Reiser is allowed
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  19) to license code labeled as owned by you on your behalf other than
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  20) under the GPL, because he wants to know if it is okay to do so and put
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  21) a check in the mail to you (for non-trivial improvements) when he
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  22) makes his next sale.  He makes no guarantees as to the amount if any,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  23) though he feels motivated to motivate contributors, and you can surely
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  24) discuss this with him before or after contributing.  You have the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  25) right to decline to allow him to license your code contribution other
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  26) than under the GPL.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  27) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  28) Further licensing options are available for commercial and/or other
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  29) interests directly from Hans Reiser: hans@reiser.to.  If you interpret
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  30) the GPL as not allowing those additional licensing options, you read
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  31) it wrongly, and Richard Stallman agrees with me, when carefully read
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  32) you can see that those restrictions on additional terms do not apply
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  33) to the owner of the copyright, and my interpretation of this shall
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  34) govern for this license.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  35) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  36) Finally, nothing in this license shall be interpreted to allow you to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  37) fail to fairly credit me, or to remove my credits, without my
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  38) permission, unless you are an end user not redistributing to others.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  39) If you have doubts about how to properly do that, or about what is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  40) fair, ask.  (Last I spoke with him Richard was contemplating how best
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  41) to address the fair crediting issue in the next GPL version.)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  52) mkreiserfs and other utilities are in reiserfs/utils, or wherever your
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  53) Linux provider put them.  There is some disagreement about how useful
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  54) it is for users to get their fsck and mkreiserfs out of sync with the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  55) version of reiserfs that is in their kernel, with many important
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  56) distributors wanting them out of sync.:-) Please try to remember to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  57) recompile and reinstall fsck and mkreiserfs with every update of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  58) reiserfs, this is a common source of confusion.  Note that some of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  59) utilities cannot be compiled without accessing the balancing code
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  60) which is in the kernel code, and relocating the utilities may require
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  61) you to specify where that code can be found.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  62) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  63) Yes, if you update your reiserfs kernel module you do have to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  64) recompile your kernel, most of the time.  The errors you get will be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  65) quite cryptic if your forget to do so.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  66) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  67) Real users, as opposed to folks who want to hack and then understand
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  68) what went wrong, will want REISERFS_CHECK off.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  81) To understand the code, after reading the website, start reading the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  82) code by reading reiserfs_fs.h first.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  84) Hans Reiser was the project initiator, primary architect, source of all
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  85) funding for the first 5.5 years, and one of the programmers.  He owns
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  86) the copyright.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  87) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  88) Vladimir Saveljev was one of the programmers, and he worked long hours
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  89) writing the cleanest code.  He always made the effort to be the best he
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  90) could be, and to make his code the best that it could be.  What resulted
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  91) was quite remarkable. I don't think that money can ever motivate someone
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  92) to work the way he did, he is one of the most selfless men I know.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  97) Anatoly Pinchuk is a former member of our team who worked closely with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  98) Vladimir throughout the project's development.  He wrote a quite
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  99) substantial portion of the total code.  He realized that there was a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 100) space problem with packing tails of files for files larger than a node
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 101) that start on a node aligned boundary (there are reasons to want to node
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 102) align files), and he invented and implemented indirect items and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 103) unformatted nodes as the solution.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 104) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) Konstantin Shvachko, with the help of the Russian version of a VC,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106) tried to put me in a position where I was forced into giving control
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 107) of the project to him.  (Fortunately, as the person paying the money
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 108) for all salaries from my dayjob I owned all copyrights, and you can't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 109) really force takeovers of sole proprietorships.)  This was something
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 110) curious, because he never really understood the value of our project,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 111) why we should do what we do, or why innovation was possible in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 112) general, but he was sure that he ought to be controlling it.  Every
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 113) innovation had to be forced past him while he was with us.  He added
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 114) two years to the time required to complete reiserfs, and was a net
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 115) loss for me.  Mikhail Gilula was a brilliant innovator who also left
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 116) in a destructive way that erased the value of his contributions, and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 117) that he was shown much generosity just makes it more painful.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 118) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 119) Grigory Zaigralin was an extremely effective system administrator for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 120) our group.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 121) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 122) Igor Krasheninnikov was wonderful at hardware procurement, repair, and

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 124) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 125) Jeremy Fitzhardinge wrote the teahash.c code, and he gives credit to a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 126) textbook he got the algorithm from in the code.  Note that his analysis
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 127) of how we could use the hashing code in making 32 bit NFS cookies work
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 128) was probably more important than the actual algorithm.  Colin Plumb also
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 129) contributed to it.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 130) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 131) Chris Mason dived right into our code, and in just a few months produced
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 132) the journaling code that dramatically increased the value of ReiserFS.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 133) He is just an amazing programmer.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 135) Igor Zagorovsky is writing much of the new item handler and extent code

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 138) Alexander Zarochentcev (sometimes known as zam, or sasha), wrote the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 139) resizer, and is hard at work on implementing allocate on flush.  SGI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 140) implemented allocate on flush before us for XFS, and generously took
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 141) the time to convince me we should do it also.  They are great people,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 142) and a great company.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 149) the endian safe patches which allow ReiserFS to run on any platform
