6 This file is a registry of magic numbers which are in use. When you
7 add a magic number to a structure, you should also add it to this
8 file, since it is best if the magic numbers used by various structures
11 It is a **very** good idea to protect kernel data structures with magic
19 The way to use magic numbers is to declare them at the beginning of

38 The magic table is current to Linux 2.1.55.
