commitID:4ab11d5bbccb8386267400f22530ccaf27cdb0b2
lwp_syscall.c中的sys_open(const char *name, int flag, ...)函数没有保留mode参数，导致移植或自己实现文件系统时比较麻烦。

Research direction
Start in lwp_syscall.c at sys_open(const char *name, int flag, ...), and inspect how its variadic arguments are handled. Check the expected open mode behavior for portability and custom filesystems, then ensure the mode argument is retained rather than lost. Done means callers can provide a mode successfully.
