68 | * Version negotiation: | |
69 | * | |
70 | * Both the kernel and userspace send the version they support in the | |
71 | * INIT request and reply respectively. | |
72 | * | |
73 | * If the major versions match then both shall use the smallest | |
74 | * of the two minor versions for communication. | |
75 | * | |
76 | * If the kernel supports a larger major version, then userspace shall | |
77 | * reply with the major version it supports, ignore the rest of the | |
78 | * INIT message and expect a new INIT message from the kernel with a | |
79 | * matching major version. | |
80 | * | |
81 | * If the library supports a larger major version, then it shall fall | |
82 | * back to the major protocol version sent by the kernel for | |
83 | * communication and reply with that major version (and an arbitrary | |
84 | * supported minor version). | |
