selftests/bpf/test_maps: exit child process without error in ENOMEM case
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 CC: Alexei Starovoitov <alexei.starovoitov@gmail.com> CC: Philip Li <philip.li@intel.com> Suggested-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Li Zhijian <zhijianx.li@intel.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
