函数原型：static void vmap_init_free_space(void)

返回类型：void

参数：无

1900  vmap_start等于1
1901  vmap_end等于ULONG_MAX
1911  如果va_start减vmap_start大于0则
1912  free等于Shortcuts
1913  如果非WARN_ON_ONCE(!free)则
1914  va_start等于vmap_start
1915  va_end等于va_start
1917  insert_vmap_area_augment(free, NULL, & This augment red-black tree represents the free vmap space, & This linked list is used in pair with free_vmap_area_root.* It gives O(1) access to prev/next to perform fast coalescing.)
1923  vmap_start等于va_end
1926  如果vmap_end减vmap_start大于0则
1927  free等于Shortcuts
1928  如果非WARN_ON_ONCE(!free)则
1929  va_start等于vmap_start
1930  va_end等于vmap_end
1932  insert_vmap_area_augment(free, NULL, & This augment red-black tree represents the free vmap space, & This linked list is used in pair with free_vmap_area_root.* It gives O(1) access to prev/next to perform fast coalescing.)
