58 | * Version negotiation: | |
59 | * | |
60 | * Both the kernel and userspace send the version they support in the | |
61 | * INIT request and reply respectively. | |
62 | * | |
63 | * If the major versions match then both shall use the smallest | |
64 | * of the two minor versions for communication. | |
65 | * | |
66 | * If the kernel supports a larger major version, then userspace shall | |
67 | * reply with the major version it supports, ignore the rest of the | |
68 | * INIT message and expect a new INIT message from the kernel with a | |
69 | * matching major version. | |
70 | * | |
71 | * If the library supports a larger major version, then it shall fall | |
72 | * back to the major protocol version sent by the kernel for | |
73 | * communication and reply with that major version (and an arbitrary | |
74 | * supported minor version). | |
