   1 # Work-around for distro-specific public modules ABI breakages.
   2 # Some distributions break the public module instrumentation ABI
   3 # compared to upstream stable kernels without providing other mean than
   4 # the kernel EXTRAVERSION to figure it out. Translate this information
   5 # into a define visible from the C preprocessor.
