[PATCH v2 6/8] memblock tests: update alloc_nid_api to test memblock_alloc_try_nid_raw
From: Rebecca Mckeever
Date: Fri Aug 19 2022 - 04:50:47 EST
Update memblock_alloc_try_nid() tests so that they test either
memblock_alloc_try_nid() or memblock_alloc_try_nid_raw() depending on the
value of alloc_nid_test_flags. Run through all the existing tests in
alloc_nid_api twice: once for memblock_alloc_try_nid() and once for
memblock_alloc_try_nid_raw().
When the tests run memblock_alloc_try_nid(), they test that the entire
memory region is zero. When the tests run memblock_alloc_try_nid_raw(),
they test that the entire memory region is nonzero.
