Subject: [PATCH bpf-next] bpf: Use kvfree() in xdp_test_run_teardown()
Date: Thu,  3 Sep 2026 18:43:58 +0800	[thread overview]
Message-ID: <20260903104358.29228-1-running910@gmail.com> (raw)

xdp_test_run_setup() allocates xdp->frames and xdp->skbs with
kvmalloc_array(). The setup error path already releases both arrays with
kvfree(), while the normal teardown path still uses kfree().

Use kvfree() in xdp_test_run_teardown() as well, so the release helper
matches the allocator on both paths.
