Subject[PATCH 0/4] memblock tests: add NUMA tests for memblock_alloc_try_nid*
Date
These patches add additional tests for memblock_alloc_try_nid() and
memblock_alloc_try_nid_raw() that use a simulated physical
memory that is set up with multiple NUMA nodes. Additionally, most of
these tests set nid != NUMA_NO_NODE.

To set up a simulated physical memory with multiple NUMA nodes, patch 1
introduces setup_numa_memblock_generic() and setup_numa_memblock().
These functions use a previously allocated dummy physical memory. They
can be used in place of setup_memblock() in tests that need to simulate
a NUMA system.

These tests are run twice, once for memblock_alloc_try_nid() and once
for memblock_alloc_try_nid_raw(), so that both functions are tested with
the same set of tests. 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.

Note:
This patchset depends on the following patch set:
