About a year ago, there was a patch produced to implement gcov support for the Linux kernel. After applying this patch and rebuilding the kernel, the standard gcovprogram can be used to see code coverage at the kernel level. For example, the attr.c file has 70.34% test coverage provided by the LTP test cases.

We implemented gcov support for the linux kernel, by providing coverage support infrastructure to the kernel and a dynamic module (gcov-prof.o) to produce the basic block profile information, which gives the statistics for the running kernel and modules. Installing GCOV support on the kernel -----
