'type' is not fixed at compile time, which means that the switch-statement cannot be optimised down. With your original patch, for example, the following code seems to simplify quite nicely from: int test_kmap(struct page *page) { int *p, q; p = kmap_atomic(page, KM_USER0); q = *p; kunmap_atomic(page, KM_USER0); return q; } to: int test_kmap(struct page *page) { int *p, q; p = kmap_atomic(page); q = *p; kunmap_atomic(page); return q; } but, the assembly goes from: 000002a0
