Hi Jens,
I needed to follow practical block I/O request behavior and was new to
blktrace. So I read the docs, noted down where I had questions, did
code history research, and collected my experience during practical
use. This is the result, hoping somebody else might find it useful.
Patches 1-20 are documentation updates (incl. tool usage output).
While I synchronized the man page updates mostly into blktrace.tex,
some things such as option details did not fit nicely into the latex
tables. Removing the 2 reference sections for blktrace(8) and
blkparse(1) from the tex file and instead referring to the man pages
would be an option to avoid sync issues. But then again, I guess the
tex file was the origin for the man pages in the first place.
Patches 21-23 are small bugfixes.
Patches 24-31 are small enhancements.
