[PATCH 6.1 0226/1146] selftests/bpf: fix missing BPF object files

Greg Kroah-Hartman
2022-12-28T15:27:46Z

From: Wang Yufen <wangyufen@huawei.com>

[ Upstream commit 98af3746026c3eccb51b43181c41e001fe73f7af ]

After commit afef88e65554 ("selftests/bpf: Store BPF object files with
.bpf.o extension"), we should use *.bpf.o instead of *.o.

In addition, use the BPF_FILE variable to save the BPF object file name,
which can be better identified and modified.

Fixes: afef88e65554 ("selftests/bpf: Store BPF object files with .bpf.o extension")
