The above error (and this is not confined to just DNETMAP) seems to be 
caused by CONFIG_UIDGID_STRICT_TYPE_CHECKS. When this is set, together 
with CONFIG_PROC_FS also being enabled in the kernel, the uid and gid 
fields of proc_dir_entry (proc_fs.h) are no longer "unsigned int", but a 
struct types, so they should be accessed/set with uid.val and gid.val 
instead - at least that is how I managed to get it work. I'll attach a 
patch if there is interest in fixing this bug - just let me know.
