Hi,

Thanks for all your answers. I have one more question, referring to the file 
"/usr/src/sys/fs/adosfs/advfsops.c", and the module 
"/usr/src/sys/lkm/vfs/adosfs":

The following function is linked into the "adosfs" module, but is defined 
nowhere:

int (**adosfs_vnodeop_p) __P((void *));

I tried to make my own "devfs_vnodeop_p" in my own module, but when loading my 
module, this symbol is undefined.

Can someone explain where such functions are defined, and what they do ?
