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
structured.
Yury Umanets (aka Umka) developed libreiser4, userspace plugins, and all
userspace tools (reiser4progs) except of fsck.
