[PATCH 19/20] perf test: bpf: free obj_buf

From: Riccardo Mancini <hidden>
Date: 2021-07-15 16:08:22
Also in: lkml
Subsystem: performance events subsystem, the rest · Maintainers: Peter Zijlstra, Ingo Molnar, Arnaldo Carvalho de Melo, Namhyung Kim, Linus Torvalds

ASan reports some memory leaks when running the 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.
