Now that makes very much sense. I have a version of the LZMA decompression
code which has been converted to Linux kernel coding style and will be
sending that for review soon.

This leaves the problem that LZMA compression code is C++. Two ideas:
* call lzma compressor as usermode helper (nasty!)
* make lzma compressed files readonly (not modifiable, but deletable)
  and give userspace the ability to directly write compressed lzma files.
