memblock tests: add bottom-up NUMA tests for memblock_alloc_try_nid*
Add tests for memblock_alloc_try_nid() and memblock_alloc_try_nid_raw() where the simulated physical memory is set up with multiple NUMA nodes. Additionally, all of these tests set nid != NUMA_NO_NODE. These tests are run with a bottom-up allocation direction. The tested scenarios are: Range unrestricted: - region can be allocated in the specific node requested: + there are no previously reserved regions + the requested node is partially reserved but has enough space - the specific node requested cannot accommodate the request, but the region can be allocated in a different node: + there are no previously reserved regions, but node is too small + the requested node is fully reserved + the requested node is partially reserved and does not have enough space Range restricted: - region can be allocated in the specific node requested after dropping min_addr: + range partially overlaps with two different nodes, where the first node is the requested node + range partially overlaps with two different nodes, where the requested node ends before min_addr - region cannot be allocated in the specific node requested, but it can be allocated in the requested range: + range overlaps with multiple nodes along node boundaries, and the requested node ends before min_addr + range overlaps with multiple nodes along node boundaries, and the requested node starts after max_addr - region cannot be allocated in the specific node requested, but it can be allocated after dropping min_addr: + range partially overlaps with two different nodes, where the second node is the requested node Acked-by: David Hildenbrand <david@redhat.com> Signed-off-by: Rebecca Mckeever <remckee0@gmail.com> Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Link: https://lore.kernel.org/r/00c4810daaf5d050abc71915b24ed7419bb16b51.1663046060.git.remckee0@gmail.com
