Log Message:
define dummy VFS_PROTOS(fsname) which is otherwise only available under _KERNEL.
lsof for legacy reasons includes sys/mount.h without _KERNEL but
msdosfs/msdosfsmount.h with _KERNEL.
Fixes:
/usr/include/msdosfs/msdosfsmount.h:255:12: error: a parameter list without \ 
types is only allowed in a function definition
