This was true at one stage but I remember some work was done to make
You should not need this. modules always call functions in the kernel for
lock operations and this functions are what invoke WITNESS.
that's what I thought but empirical evidence disagrees.
I'll try some more cases.
I swap back and forth all the time between the two. Kernel modules don’t
