A Bug in linker_reference_module() ?

[Intron is my alias on the Internet]

Please have a look at the function linker_reference_module() in
/sys/kern/kern_linker.c of 7.0-CURRENT. If the module is loaded on demand,
why not increase its reference counter after loading? In my opinion,
linker_reference_module() behaves differently from linker_load_file().
