Martin KaFai Lau 3fbfadce60 bpf: Fix test_lru_sanity5() in test_lru_map.c ... test_lru_sanity5() fails when the number of online cpus is fewer than the number of possible cpus. It can be reproduced with qemu by using cmd args "--smp cpus=2,maxcpus=8". The problem is the loop in test_lru_sanity5() is testing 'i' which is incorrect. This patch: 1. Make sched_next_online() always return -1 if it cannot find a next cpu to schedule the process. 2. In test_lru_sanity5(), the parent process does sched_setaffinity() first (through sched_next_online()) and the forked process will inherit it according to the 'man sched_setaffinity'.
