Rename the following places: - struct create_durable -> CREATE_DURABLE_REQ - struct create_durable_reconn_req -> CREATE_DURABLE_RECONN The documentation references are: - SMB2_CREATE_DURABLE_HANDLE_REQUEST in MS-SMB2 2.2.13.2.3 - SMB2_CREATE_DURABLE_HANDLE_RECONNECT in MS-SMB2 2.2.13.2.4 - SMB2_FILEID in MS-SMB2 2.2.14.1 Descriptions of the struct fields: - __u8 Reserved[16]: DurableRequest field of SMB2_CREATE_DURABLE_HANDLE_REQUEST. A 16-byte field that MUST be reserved. - __u64 PersistentFileId: Persistent field of 2.2.14.1 SMB2_FILEID - __u64 VolatileFileId: Volatile field of 2.2.14.1 SMB2_FILEID - struct Fid: Data field of SMB2_CREATE_DURABLE_HANDLE_RECONNECT. An SMB2_FILEID structure, as specified in section 2.2.14.1.
