SVN rev 198706 on 2009-10-31 10:35:41Z by ed
Turn unused structure fields of cdevsw into spares.
d_uid, d_gid and d_mode are unused, because permissions are stored in
cdevpriv nowadays. d_kind doesn't seem to be used at all. We no longer
keep a list of cdevsw's, so d_list is also unused.
uid_t and gid_t are 32 bits, but mode_t is 16 bits, Because of alignment
constraints of d_kind, we can safely turn it into three 32-bit integers.
d_kind and d_list is equal in size to three pointers.
