我出于某种原因为内核移植了一些功能，我遇到了大量的错误消息。其中大部分是我修复过的。
我主要处理头文件以根据我的需要调整它们。获取以下大约92条错误消息：
include/linux/dax.h:66:26: error: dereferencing pointer to incomplete type
include/linux/highmem.h:67:18: error: dereferencing pointer to incomplete type
include/linux/pagemap.h:66:28: error: dereferencing pointer to incomplete type
include/linux/backing-dev-defs.h:191:22: error: dereferencing pointer to incomplete type
include/linux/writeback.h:217:13: error: dereferencing pointer to incomplete type
include/linux/blkdev.h:972:32: error: dereferencing pointer to incomplete type
include/linux/fsnotify_backend.h:317:13: error: dereferencing pointer to incomplete type
include/linux/fsnotify.h:218:12: error: dereferencing pointer to incomplete type
include/linux/fs.h:776:18: error: dereferencing pointer to incomplete type
include/linux/backing-dev.h:66:45: error: dereferencing pointer to incomplete type
关于如何修复它而不重写再次加载功能的任何原型？ 这些头文件中有很多结构用法。例如：
struct page;
