If the CONFIG_FRAME_POINTER option was set during kernel compilation, the frame pointer register is used to maintain stacks and, hence, the stack traceback can be performed correctly.

如果内核编译期间设置了CONFIG_FRAME _ POINTER选项，那么就用帧指针寄存器来维护堆栈，从而就可以正确地执行堆栈回溯。

For example, if you enable the Z shell option pushd_ignore_dups, pushd won't push a directory onto the directory stack if it's already there.

例如，如果已经启用了Z shell选项pushd_ignore_dups, pushd就不会将已存在的目录压入目录堆栈。
