I spent most of yesterday going through all the documentation bits in the utrace patch. The Documentation/utrace.txt file is gone now, and everything is in DocBook instead.
I went through all the text and rewrote bits to match the new interface. I reviewed and updated all the kerneldoc comments. The 'make htmldocs' pages look decent (I didn't look at other output formats). Please review all this text and give me any feedback ASAP. This cosmetic update was the main thing I wanted to finish before submitting the code upstream, now that I've sent tracehook. Of course, I'll be looking at the recent bugs too. But I expect more upstream feedback about the trivia and cosmetic issues than anything actually subtle that requires really thinking about using the interface as folks here do. The aesthetics will be the likely barrier to acceptance, not whether the new experimental code is still buggy. Thanks, Roland
