* The kernel version has been converted from a string to a four-byte
|
|
* quantity that is divided into two parts.
|
|
*
|
|
* Part 1: The three most significant bytes represent the kernel's
|
|
* numeric version, x.y.z. These fields denote:
|
|
* x -- major release
|
|
* y -- minor release
|
|
* z -- patchlevel release
|
|
* Each of these elements must therefore be in the range 0 to 255, inclusive.
|
|
*
|
|
* Part 2: The least significant byte is reserved for future use.
