Here. if (IS_ENABLED(CONFIG_COMMAND_SUPPORT)) { pr_info("running /env/bin/init...\n"); if (!stat("/env/bin/init", &s)) run_command("source /env/bin/init"); else pr_err("/env/bin/init not found\n"); } My configuration is very minimal for now. I do not have (yet) any FS selected (excepted devfs) and I do not have any root device mounted either in this configuration. I guess this is why fs_dev_root is NULL and why get_fsdevice_by_path() returns fs_dev_root (because there is nothing to iterate in list fs_device_list).
