[PATCH bpf-next] selftests/bpf: Don't assume page size is 4096

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The verifier test creates BPF ringbuf maps using hard-coded
4096 as max_entries. Some tests will fail if the page size
of the running kernel is not 4096. Use getpagesize() instead.
