我正在尝试为 arm 交叉编译 Linux 内核 4.10.8，但出现此错误：

      CC [M]  drivers/vhost/vhost.o
In file included from ./include/uapi/linux/stddef.h:1:0,
                 from ./include/linux/stddef.h:4,

                 from ./include/uapi/linux/types.h:13,

                 from ./include/linux/eventfd.h:11,
                 from drivers/vhost/vhost.c:14:

  _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)enter

知道如何解决这个问题吗？我不知道这个模块是用来做什么的，所以我不知道我是否真的需要编译它，但是我在 menuconfig 中找不到禁用这个模块的地方？

此模块 (CONFIG_VHOST) 通常在您需要virtualization支持时需要。如果您不需要它，请在make menuconfig.

如果您不需要虚拟化，您可以忽略它并继续构建。
