函数名称：We should probably have a fallback mechanism to allocate virtual memory* out of partially filled vmap blocks. However vmap block sizing should be* fairly reasonable according to the vmalloc size, so it shouldn't be a* big problem.
函数原型：static unsigned long addr_to_vb_idx(unsigned long addr)
返回类型：unsigned long
参数：
| 类型 | 参数 | 名称 |
|---|---|---|
| unsigned long | addr |
| 1468 | addr减等于VMALLOC_START按位与VMAP_BLOCK_SIZE减1的差的反 |
| 1469 | addr除等于VMAP_BLOCK_SIZE |
| 1470 | 返回:addr |
| 名称 | 描述 |
|---|---|
| vmap_block_vaddr | |
| new_vmap_block | w_vmap_block - allocates new vmap_block and occupies 2^order pages in this* block |
| free_vmap_block | |
