The issue I have with this, is that I run these tests on older kernels too, and tests that use to work on older kernels should still work. In fact, this fails on the kernel I'm currently adding new changes to!
Perhaps we should have:
# older kernels have do_fork, but newer kernels have kernel_clone echo kernel_clone >> set_ftrace_filter || echo *do_fork >> set_ftrace_filter
The above still seems to work for me.
