Subject: [PATCH 4.4 21/47] perf test bpf: Free obj_buf
Date: Mon, 26 Jul 2021 17:38:39 +0200	[thread overview]
Message-ID: <20210726153823.647791438@linuxfoundation.org> (raw)
In-Reply-To: <20210726153822.980271128@linuxfoundation.org>

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.
