dtrace for linux

[fox@crisp.demon.co.uk]

I would like to announce that I am working on dtrace for Linux.
I have the userland dtrace binary compiled, along with the first
pre-pre-alpha dtracedrv.ko module loaded into my kernel.

Its early days as I work thru the issues but am into stage 3.

Stage 1 was to compile userland dtrace and stage 2 was to compile
the kernel driver. I have lots of stubs and likely bad #defines.

I am trying to improve my makefiles and header dependencies so I
can validate some aspects of kernel portability.

If anyone wants to grab a copy (purely for reference - dont try and
run anything), you can visit 

http://www.crisp.demon.co.uk/tools

and pick up a daily snapshot.

If anyone wants to contribute, feel free - especially if you
feel the approach is wrong etc.

I wont talk about licensing - except to say it will be covered
by the CDDL and not GPL, since its Sun's work and I am simply
deriving, and I am not modifying the kernel (yet).
