So, it appears that certain kernel developers are deliberately crippling Reiser4. Or, perhaps, Hans Reiser and the Namesys developers are just much better coders, and the kernel developers adjustments, have just made good code, bad. Certainly, many people have been lying about the qualities and abilities of the Reiser4 filesystem, and such active sabotage, by a few developers, is the most likely explanation.
Malice is not the only explanation. Apathy fits just fine. Try not to be so quick to jump to conspiracy theory.
