I don't know that we have any tools that have been used for code

coverage. What tools do you use to get code coverage data for the

linux kernel?

There is a patch that allows kernel to be compiled with -fprofile-arcs and -ftest-coverage. gcov input data (.bb files) are dynamically exported in /proc file system.
