Other .bdrv_open() methods do it similarly. * qemu_rbd_open() accepts additional list-valued options auth-supported and server, with the help of qemu_rbd_array_opts(). The list elements are again dictionaries. qemu_rbd_array_opts() uses runtime_opts to accept their members. Thus, runtime_opts contains recognized sub-sub-options "auth", "host", "port" in addition to recognized options. No other block driver does that. * qemu_rbd_create() uses it to convert the QDict produced by qemu_rbd_parse_filename() to QemuOpts. No other block driver does that. The keys produced by qemu_rbd_parse_filename() are "pool", "image", "snapshot", "conf", "user" and "keyvalue-pairs". qemu_rbd_open() accepts these, so no additional ones here. This is a confusing mess. Dates back to commit 0f9d252. First step to clean it up is documenting runtime_opts.desc[]: * Reorder entries to match the QAPI schema, like we do in other block drivers. * Document why the schema's "server" and "auth-supported" aren't in .desc[]. * Document why "keyvalue-pairs", "host", "port" and "auth" are in .desc[], but not the schema. * Delete "filename", because none of the three users actually uses it. This fixes -drive to reject parameter filename instead of silently ignoring it.
