Hans Reiser was the project initiator, source of all funding for the first 5.5
years. He is the architect and official maintainer.
Vladimir Saveliev started as the most junior programmer on the team, and became
the lead programmer. He is now an experienced highly productive programmer. He
wrote the extent handling code for Reiser4, plus parts of the balancing code
and file write and file read.
Alexander Zarochentcev (zam) wrote the high low priority locking code, online
resizer for V3 and V4, online repacker for V4, block allocation code, and major
parts of the flush code, and maintains the transaction manager code. We give
him the stuff that we know will be hard to debug, or needs to be very cleanly
Nikita Danilov wrote most of the core balancing code, plugin infrastructure,
and directory code. He steadily worked long hours, and is the reason so much of
the Reiser4 plugin infrastructure is well abstracted in its details. The carry
function, and the use of non-recursive balancing, are his idea.
Vladimir Demidov wrote the parser for sys_reiser4(), the V3 alpha port, part of
the V3 journal relocation code, and helped Hans keep the business side of
Chris Mason wrote the journaling code for V3, which was enormously more useful
to users than just waiting until we could create a wandering log filesystem as
Hans would have unwisely done without him.
Jeff Mahoney optimized the bitmap scanning code for V3, and performed the big
Elena Gryaznova performed testing and benchmarking.
Oleg Drokin was the debugger for V3 during most of the time that V4 was under
development, and was quite skilled and fast at it. He wrote the large write
optimization of V3.
Edward Shishkin wrote the encryption and compression file plugins, and the V3
journal relocation code.
Alexander Lyamin keeps our hardware running, and was very generous to our
project in many little ways.
Vitaly Fertman wrote fsck for V3 and maintains the reiserfsprogs package now.
He wrote librepair, userspace plugins repair code, fsck for V4, and worked on
developing libreiser4 and userspace plugins with Umka.
Yury Umanets (aka Umka) developed libreiser4, userspace plugins, and all
userspace tools (reiser4progs) except of fsck.
Joshua Macdonald wrote the first draft of the transaction manager. Yuri Rupasov
did testing and benchmarking, plus he invented the r5 hash (also used by the
dcache code). Yura Rupasov, Anatoly Pinchuk, Igor Krasheninnikov, Grigory
Zaigralin, Mikhail Gilula, Igor Zagorovsky, Roman Pozlevich, Konstantin
Shvachko, and Joshua MacDonald are former contributors to the project.
Jeremy Fitzhardinge wrote the teahash.c code for V3. Colin Plumb also
contributed to that.
The Defense Advanced Research Projects Agency (DARPA, www.darpa.mil) is the
primary sponsor of Reiser4. DARPA does not endorse this project; it merely
Continuing core development of ReiserFS is mostly paid for by Hans Reiser from
money made selling licenses in addition to the GPL to companies who don't want
it known that they use ReiserFS as a foundation for their proprietary product.
And my lawyer asked 'People pay you money for this?'. Yup. Life is good. If you
buy ReiserFS, you can focus on your value add rather than reinventing an entire
BigStorage (www.bigstorage.com) contributes to our general fund every month,
and has done so for quite a long time.
SuSE (www.suse.com) pays for continuing work on journaling for version 3, paid
for much of the previous version 3 work, and is paying for Chris and Jeff to do
V3 maintenance. Reiserfs integration in their distro is consistently solid, and
they were key to our becoming widely used.
Lycos Europe (www.lycos-europe.com) had a support contract with us that
consistently came in just when we would otherwise have missed payroll, and that
they kept doubling every year. Much thanks to them.
Many persons came to www.namesys.com/support.html, and got a question answered
for $25, or just gave us a small donation there.
Thanks to all of those sponsors, including the secret ones. Without you, we
would each still have that day job.
