 208 #       The global lint target builds the kernel lint library (llib-lunix.ln)
 209 #       which is equivalent to a lint of /unix.o. Then all kernel modules for
 210 #       this architecture are linted against the kernel lint library.
 211 #
 212 #       Note:   lint errors in the kernel lint library will be repeated for
 213 #               each module. It is important that the kernel lint library
 214 #               be clean to keep the textual output to a reasonable level.
