Grow_continue_command() call verify_reshape_position(), which assumes that info->sys_name is initialised. 'info' in verify_reshape_position() is 'content' in Grow_continue_command(). In the st->ss->external != 0 branch of that function, sysfs_init() is called to initialize content->sys_name. In the st->ss->external == 0 branch, ->sys_name is not initialized so verify_reshape_position() will not do the right thing.
