Tomek, I'm looking through your patch example/fio: add option to load json_config [1] and have some concerns to the overall design of applications utilizing SPDK without the app framework. First of all, we seem to use spdk_app_json_config_load() to load a JSON config in fio_plugin. The spdk_app_ prefix in that function suggests it's the app framework API, which we don't use in fio_plugin. I'm guessing it should be at least renamed? spdk_json_config_load() maybe?
spdk_app_json_config_load() is defined in spdk_internal/event.h. Why is this internal anyway? This practically forces external SPDK users to stick with either legacy json config files, or spdk_app_start(). The question is where should we move it? lib/event.h is currently specific to the app framework. Do you have any plans for SPDK app design without the app framework? I'm guessing we do want to support it (see fio_plugin), but currently it's messy.
D.
