[Qemu-devel] [PULL 10/12] NUMA: Replace MAX_NODES with nb_numa_nodes in


From: Eduardo Habkost
Subject: [Qemu-devel] [PULL 10/12] NUMA: Replace MAX_NODES with nb_numa_nodes in for loop
Date: Tue, 19 Sep 2017 17:18:48 -0300

From: Dou Liyang <address@hidden>

In QEMU, the number of the NUMA nodes is determined by parse_numa_opts().
Then, QEMU uses it for iteration, for example:
  for (i = 0; i < nb_numa_nodes; i++)

However, in memory_region_allocate_system_memory(), it uses MAX_NODES
not nb_numa_nodes.

So, replace MAX_NODES with nb_numa_nodes to keep code consistency and
reduce the loop times.
