    sys/sys              module.h 
  Log:
  Add an automatic kernel module version dependency to prevent loading
  modules using invalid ABI versions (e.g. a 7.x module with an 8.x kernel)
  for a given kernel:
  - Add a 'kernel' module version whose value is __FreeBSD_version.
  - Add a version dependency on 'kernel' in every module that has an
    acceptable version range of __FreeBSD_version up to the end of the
    branch __FreeBSD_version is part of.  E.g. a module compiled on 701000
    would work on kernels with versions between 701000 and 799999 inclusive.
