-/*
-As a preparation for the introduction of larger device numbers,
-we introduce a type kdev_t to hold them. No information about
-this type is known outside of this include file.
-
-Objects of type kdev_t designate a device. Outside of the kernel
-the corresponding things are objects of type dev_t - usually an
-integral type with the device major and minor in the high and low
-bits, respectively. Conversion is done by
-
-extern kdev_t to_kdev_t(int);
-
-It is up to the various file systems to decide how objects of type
-dev_t are stored on disk.
-The only other point of contact between kernel and outside world
-are the system calls stat and mknod, new versions of which will
-eventually have to be used in libc.
-
-[Unfortunately, the floppy control ioctls fail to hide the internal
-kernel structures, and the fd_device field of a struct floppy_drive_struct
-is user-visible. So, it remains a dev_t for the moment, with some ugly
-conversions in floppy.c.]
-
-Inside the kernel, we aim for a kdev_t type that is a pointer
-to a structure with information about the device (like major,
-minor, size, blocksize, sectorsize, name, read-only flag,
-struct file_operations etc.).
-
-However, for the time being we let kdev_t be almost the same as dev_t:
-
-typedef struct { unsigned short major, minor; } kdev_t;
-
-Admissible operations on an object of type kdev_t:
-- passing it along
-- comparing it for equality with another such object
-- storing it in inode->i_rdev or tty->device
-- using its bit pattern as argument in a hash function
-- finding its major and minor
-- complaining about it
-
-An object of type kdev_t is created only by the function MKDEV(),
-with the single exception of the constant 0 (no device).
-
-Right now the other information mentioned above is usually found
-in static arrays indexed by major or major,minor.
-
-An obstacle to immediately using
-    typedef struct { ... (* lots of information *) } *kdev_t
-is the case of mknod used to create a block device that the
-kernel doesn't know about at present (but first learns about
-when some module is inserted).
