75 Using kmap_atomic
78 When and where to use kmap_atomic() is straightforward. It is used when code
87 void *vaddr = kmap_atomic(page);
95 Note that the kunmap_atomic() call takes the result of the kmap_atomic() call
99 another you need to keep the kmap_atomic calls strictly nested, like::
101 vaddr1 = kmap_atomic(page1);
102 vaddr2 = kmap_atomic(page2);
