  1 [LICENSING]
  2 
  3 ReiserFS is hereby licensed under the GNU General
  4 Public License version 2.
  5 
  6 Source code files that contain the phrase "licensing governed by
  7 reiserfs/README" are "governed files" throughout this file.  Governed
  8 files are licensed under the GPL.  The portions of them owned by Hans
  9 Reiser, or authorized to be licensed by him, have been in the past,
 10 and likely will be in the future, licensed to other parties under
 11 other licenses.  If you add your code to governed files, and don't
 12 want it to be owned by Hans Reiser, put your copyright label on that
 13 code so the poor blight and his customers can keep things straight.
 14 All portions of governed files not labeled otherwise are owned by Hans
 15 Reiser, and by adding your code to it, widely distributing it to
 16 others or sending us a patch, and leaving the sentence in stating that
 17 licensing is governed by the statement in this file, you accept this.
 18 It will be a kindness if you identify whether Hans Reiser is allowed
 19 to license code labeled as owned by you on your behalf other than
 20 under the GPL, because he wants to know if it is okay to do so and put
 21 a check in the mail to you (for non-trivial improvements) when he
 22 makes his next sale.  He makes no guarantees as to the amount if any,
 23 though he feels motivated to motivate contributors, and you can surely
 24 discuss this with him before or after contributing.  You have the
 25 right to decline to allow him to license your code contribution other
 26 than under the GPL.
 27 
 28 Further licensing options are available for commercial and/or other
 29 interests directly from Hans Reiser: hans@reiser.to.  If you interpret
 30 the GPL as not allowing those additional licensing options, you read
 31 it wrongly, and Richard Stallman agrees with me, when carefully read
 32 you can see that those restrictions on additional terms do not apply
 33 to the owner of the copyright, and my interpretation of this shall
 34 govern for this license.
 35 
 36 Finally, nothing in this license shall be interpreted to allow you to
 37 fail to fairly credit me, or to remove my credits, without my
 38 permission, unless you are an end user not redistributing to others.
 39 If you have doubts about how to properly do that, or about what is
 40 fair, ask.  (Last I spoke with him Richard was contemplating how best
 41 to address the fair crediting issue in the next GPL version.)

 45 Reiserfs is a file system based on balanced tree algorithms, which is
 46 described at https://reiser4.wiki.kernel.org/index.php/Main_Page

 48 Stop reading here.  Go there, then return.

 51 
 52 mkreiserfs and other utilities are in reiserfs/utils, or wherever your
 53 Linux provider put them.  There is some disagreement about how useful
 54 it is for users to get their fsck and mkreiserfs out of sync with the
 55 version of reiserfs that is in their kernel, with many important
 56 distributors wanting them out of sync.:-) Please try to remember to
 57 recompile and reinstall fsck and mkreiserfs with every update of
 58 reiserfs, this is a common source of confusion.  Note that some of the
 59 utilities cannot be compiled without accessing the balancing code
 60 which is in the kernel code, and relocating the utilities may require
 61 you to specify where that code can be found.
 62 
 63 Yes, if you update your reiserfs kernel module you do have to
 64 recompile your kernel, most of the time.  The errors you get will be
 65 quite cryptic if your forget to do so.
 66 
 67 Real users, as opposed to folks who want to hack and then understand
 68 what went wrong, will want REISERFS_CHECK off.
 69 
 70 Hideous Commercial Pitch: Spread your development costs across other OS
 71 vendors.  Select from the best in the world, not the best in your
 72 building, by buying from third party OS component suppliers.  Leverage
 73 the software component development power of the internet.  Be the most
 74 aggressive in taking advantage of the commercial possibilities of
 75 decentralized internet development, and add value through your branded
 76 integration that you sell as an operating system.  Let your competitors
 77 be the ones to compete against the entire internet by themselves.  Be
 78 hip, get with the new economic trend, before your competitors do.  Send
 79 email to hans@reiser.to.
 80 
 81 To understand the code, after reading the website, start reading the
 82 code by reading reiserfs_fs.h first.
 83 
 84 Hans Reiser was the project initiator, primary architect, source of all
 85 funding for the first 5.5 years, and one of the programmers.  He owns
 86 the copyright.
 87 
 88 Vladimir Saveljev was one of the programmers, and he worked long hours
 89 writing the cleanest code.  He always made the effort to be the best he
 90 could be, and to make his code the best that it could be.  What resulted
 91 was quite remarkable. I don't think that money can ever motivate someone
 92 to work the way he did, he is one of the most selfless men I know.
 93 
 94 Yura helps with benchmarking, coding hashes, and block pre-allocation
 95 code.
 96 
 97 Anatoly Pinchuk is a former member of our team who worked closely with
 98 Vladimir throughout the project's development.  He wrote a quite
 99 substantial portion of the total code.  He realized that there was a
100 space problem with packing tails of files for files larger than a node
101 that start on a node aligned boundary (there are reasons to want to node
102 align files), and he invented and implemented indirect items and
103 unformatted nodes as the solution.
104 
105 Konstantin Shvachko, with the help of the Russian version of a VC,
106 tried to put me in a position where I was forced into giving control
107 of the project to him.  (Fortunately, as the person paying the money
108 for all salaries from my dayjob I owned all copyrights, and you can't
109 really force takeovers of sole proprietorships.)  This was something
110 curious, because he never really understood the value of our project,
111 why we should do what we do, or why innovation was possible in
112 general, but he was sure that he ought to be controlling it.  Every
113 innovation had to be forced past him while he was with us.  He added
114 two years to the time required to complete reiserfs, and was a net
115 loss for me.  Mikhail Gilula was a brilliant innovator who also left
116 in a destructive way that erased the value of his contributions, and
117 that he was shown much generosity just makes it more painful.
118 
119 Grigory Zaigralin was an extremely effective system administrator for
120 our group.
121 
122 Igor Krasheninnikov was wonderful at hardware procurement, repair, and
123 network installation.
124 
125 Jeremy Fitzhardinge wrote the teahash.c code, and he gives credit to a
126 textbook he got the algorithm from in the code.  Note that his analysis
127 of how we could use the hashing code in making 32 bit NFS cookies work
128 was probably more important than the actual algorithm.  Colin Plumb also
129 contributed to it.
130 
131 Chris Mason dived right into our code, and in just a few months produced
132 the journaling code that dramatically increased the value of ReiserFS.
133 He is just an amazing programmer.
134 
135 Igor Zagorovsky is writing much of the new item handler and extent code
136 for our next major release.
137 
138 Alexander Zarochentcev (sometimes known as zam, or sasha), wrote the
139 resizer, and is hard at work on implementing allocate on flush.  SGI
140 implemented allocate on flush before us for XFS, and generously took
141 the time to convince me we should do it also.  They are great people,
142 and a great company.
143 
144 Yuri Shevchuk and Nikita Danilov are doing squid cache optimization.
145 
146 Vitaly Fertman is doing fsck.
147 
148 Jeff Mahoney, of SuSE, contributed a few cleanup fixes, most notably
149 the endian safe patches which allow ReiserFS to run on any platform
150 supported by the Linux kernel.
151 
152 SuSE, IntegratedLinux.com, Ecila, MP3.com, bigstorage.com, and the
153 Alpha PC Company made it possible for me to not have a day job
154 anymore, and to dramatically increase our staffing.  Ecila funded
155 hypertext feature development, MP3.com funded journaling, SuSE funded
156 core development, IntegratedLinux.com funded squid web cache
157 appliances, bigstorage.com funded HSM, and the alpha PC company funded
158 the alpha port.  Many of these tasks were helped by sponsors other
159 than the ones just named.  SuSE has helped in much more than just
160 funding....
