Well, I might be completely wrong, but this little bit from
$KERNEL_SRC/include/linux/coda.h has a "int" in it:

 409 /* coda_ioctl: */
 410 struct coda_ioctl_in {
 411     struct coda_in_hdr ih;
 412     struct CodaFid VFid;
 413     int cmd;
 414     int len;
 415     int rwflag;
 416     char *data;     /* Place holder for data. */
 417 };

Could anyone instruct me, how to do the cleanup - or is anyone capable of
doing it?
