From: Li Zhijian <lizhijian@xxxxxxxxxxxxxx> [ Upstream commit 2d82d73da35b72b53fe0d96350a2b8d929d07e42 ] 0Day robot observed that it's easily timeout on a heavy load host. ------------------- # selftests: bpf: test_maps # Fork 1024 tasks to 'test_update_delete' # Fork 1024 tasks to 'test_update_delete' # Fork 100 tasks to 'test_hashmap' # Fork 100 tasks to 'test_hashmap_percpu' # Fork 100 tasks to 'test_hashmap_sizes' # Fork 100 tasks to 'test_hashmap_walk' # Fork 100 tasks to 'test_arraymap' # Fork 100 tasks to 'test_arraymap_percpu' # Failed sockmap unexpected timeout not ok 3 selftests: bpf: test_maps # exit=1 # selftests: bpf: test_lru_map # nr_cpus:8 ------------------- Since this test will be scheduled by 0Day to a random host that could have only a few cpus(2-8), enlarge the timeout to avoid a false NG report. In practice, i tried to pin it to only one cpu by 'taskset 0x01 ./test_maps', and knew 10S is likely enough, but i still perfer to a larger value 30.
