 223 #       The global lint target builds the kernel lint library (llib-lunix.ln)
 224 #       which is equivalent to a lint of /unix.o. Then all kernel modules for
 225 #       this architecture are linted against the kernel lint library.

 229 #               be clean to keep the textual output to a reasonable level.
