Cleanups Applied, thanks! http://repo.or.cz/w/qemu/stefanha.git/shortlog/refs/heads/tracing I'd like to focus on polishing the current tracing branch into a patchset that can be merged into QEMU. Having this working prototype enables us to try tracing out; we can commit fixes on top and then squish the commits down for QEMU merge when the basic feature set is solid. > Todos : > 1.
