the relevant bits are ignored 相关位会被忽略
Thus, whenever instruction addresses are presented to the processor (as in Branch instructions), the low-order two bits are ignored.
因此,只要将指令地址提供给处理器(如Branch指令),就会忽略低阶的两位。
However, if a legitimate suid executable is on the same file system as a world writable directory and is thus mounted nosuid, the suid bits are ignored and the executable will not operate correctly.
然而,如果在一个合法的suid可执行程序与一个人人可写的目录在同一个文件系统中,因此使用nosuid选项来挂载的,那么sui d位就会被忽略,这个可执行程序也就无法正确执行。
