[TUHS] SCO's "evidence" (was: RIP Darl McBride former CEO of SCO)

[Larry McVoy]

The thing I never got a reasonable answer to was I found code in BSD that
was identical to code going back to at least V7.  Find bmap() in the UFS
code and then find the same in V7.  I might be wrong about V7, might be
32V, might be V6.  I don't think it matters, it's the same in all of them.

bmap() is the code that maps a logical block to a phsyical block,
I'm quite familiar with it because I rewrote it to bmap_write() and
bmap_read() as part of making UFS do extents:

When all the lawsuits were going on, since I knew that code really well,
I went off and looked and the BSD code at that time had bit for bit
identical bmap() implementations.  

I never understood why BSD could claim they rewrote everything when they
clearly had not rewritten that.

I've raised this question before and I just went and looked, bmap() has
changed.  I'm pretty sure I have Kirk's BSD source releases, if I do, 
I'm 100% sure I can back up what I'm saying.  Not sure I care enough to
do so, it's all water under the bridge at this point.
