    Subject[PATCH 4.9 32/60] perf test bpf: Free obj_buf
    Date
    From: Riccardo Mancini <rickyman7@gmail.com>

    [ Upstream commit 937654ce497fb6e977a8c52baee5f7d9616302d9 ]

    ASan reports some memory leaks when running:

    # perf test "42: BPF filter"

    The first of these leaks is caused by obj_buf never being deallocated in
    __test__bpf.

    This patch adds the missing free.
