Dcachetlb.rst313 vmap/vmalloc API设置的。由于内核I/O是通过物理页进行的，I/O子系统假定用户
314 映射和内核偏移映射是唯一的别名。这对vmap别名来说是不正确的，所以内核中任何
315 试图对vmap区域进行I/O的东西都必须手动管理一致性。它必须在做I/O之前刷新vmap
320 刷新vmap区域中指定的虚拟地址范围的内核缓存。这是为了确保内核在vmap范围
326 在vmap区域的一个给定的虚拟地址范围的缓存，这可以防止处理器在物理页的I/O
327 发生时通过投机性地读取数据而使缓存变脏。这只对读入vmap区域的数据是必要的。

Dcachetlb.rst371 vmap/vmalloc API. Since kernel I/O goes via physical pages, the I/O
373 the only aliases. This isn't true for vmap aliases, so anything in
374 the kernel trying to do I/O to vmap areas must manually manage
375 coherency. It must do this by flushing the vmap range before doing
381 the vmap area. This is to make sure that any data the kernel
382 modified in the vmap range is made visible to the physical
389 the cache for a given virtual address range in the vmap area
