linux-toradex.git/lib/uuid.c, branch v3.0.79 Linux kernel for Apalis and Colibri modules Unified UUID/GUID definition 2010-05-20T02:40:47+00:00 Huang Ying ying.huang@intel.com 2010-05-18T06:35:18+00:00 fab1c23242528771a955c475ef23d99156a71a7f There are many different UUID/GUID definitions in kernel, such as that in EFI, many file systems, some drivers, etc. Every kernel components need UUID/GUID has its own definition. This patch provides a unified definition for UUID/GUID. UUID is defined via typedef. This makes that UUID appears more like a preliminary type, and makes the data type explicit (comparing with implicit "u8 uuid[16]"). The binary representation of UUID/GUID can be little-endian (used by EFI, etc) or big-endian (defined by RFC4122), so both is defined.
