test_numa_migrate.c: In function 'parse_memory_numa_stat.isra':
test_numa_migrate.c:521:34: warning: 'node' may be used uninitialized
[-Wmaybe-uninitialized]
521 | node_stat[node] = node_bytes;
| ^
test_numa_migrate.c:485:16: note: 'node' was declared here
485 | size_t node;
| ^~~~
Initialize 'node' to 0 to silence the -Wmaybe-uninitialized warning.
The variable is always set inside the loop before use in the else branch,
but GCC cannot prove this statically.
