Re: [PATCH bpf v4 2/2] selftests/bpf: add regression test for bpf_d_path()

Hi,

I looked into the CI failure and it’s caused by the test assuming /tmp is on tmpfs, which is not true in the CI environment, so fallocate() fails there. Since /dev/shm is mounted as tmpfs on that setup, would it be acceptable to change the test to use a file under /dev/shm instead of /tmp?
