test_maps contains a series of stress tests, and previously it will break the rest tests when it failed to alloc memory. ----------------------- Failed to create hashmap key=8 value=262144 'Cannot allocate memory' Failed to create hashmap key=16 value=262144 'Cannot allocate memory' Failed to create hashmap key=8 value=262144 'Cannot allocate memory' Failed to create hashmap key=8 value=262144 'Cannot allocate memory' test_maps: test_maps.c:955: run_parallel: Assertion `status == 0' failed. Aborted not ok 1..3 selftests: test_maps [FAIL] ----------------------- after this patch, the rest tests will be continue when it occurs an ENOMEM failure
