 234 #       The global lint target builds the kernel lint library (llib-lunix.ln)
 235 #       which is equivalent to a lint of /unix.o. Then all kernel modules for
 236 #       this architecture are linted against the kernel lint library.
 237 #
 238 #       Note:   lint errors in the kernel lint library will be repeated for
 239 #               each module. It is important that the kernel lint library
 240 #               be clean to keep the textual output to a reasonable level.
