Dmemory-allocation.rst20 系列分配小块内存，使用 `vmalloc` 及其派生产品分配大的几乎连续的区域，或者
123 对于大量的分配，你可以使用vmalloc()和vzalloc()，或者直接向页面分配器请求页面。由vmalloc
127 试用kmalloc分配内存，如果分配失败，将用 `vmalloc` 重新尝试。对于哪些GFP标志可以与 `kvmalloc`
136 当分配的内存不再需要时，它必须被释放。你可以使用kvfree()来处理用 `kmalloc` 、 `vmalloc`
Dgfp_mask-from-fs-io.rst60 vmalloc不支持GFP_NOFS语义，因为在分配器的深处有硬编码的GFP_KERNEL分配，要修
61 复这些分配是相当不容易的。这意味着用GFP_NOFS/GFP_NOIO调用 ``vmalloc`` 几乎
64 在理想的世界中，上层应该已经标记了危险的上下文，因此不需要特别的照顾， ``vmalloc``
66 推荐的方法是用范围API包装vmalloc，并加上注释来解释问题。

Dgfp_mask-from-fs-io.rst58 vmalloc doesn't support GFP_NOFS semantic because there are hardcoded
60 to fix up. That means that calling ``vmalloc`` with GFP_NOFS/GFP_NOIO is
65 and so no special care is required and vmalloc should be called without
67 layering violations then the recommended way around that is to wrap ``vmalloc``
