Why dont you license the user-space library under the GPLv2?
Also, i dont agree that such interfaces should be ABIs, hence i
oppose the librarization of such raw kernel interfaces. For example
markers will be removed in the future, and tracepoints will sure
undergo more corrective iterations as well.
