Subject: selftests/bpf: Destroy XDP link correctly
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f91231eeeed752119f49eb6620cae44ec745a007;p=linux.git

selftests/bpf: Destroy XDP link correctly

bpf_link__detach() was confused with bpf_link__destroy() and leaves
leaked FD in the process. Fix the problem.
