From 652f0c2c999d28d820bbe2e1aa16d8e0fea369ea Mon Sep 17 00:00:00 2001 From: Leon Hwang Date: Mon, 18 May 2026 22:54:45 +0800 Subject: [PATCH] selftests/bpf: Use -1 as token_fd in map create failure test Because 0xFF can be an open BPF token fd in the test runner that will fail test_invalid_token_fd(), change token_fd from 0xFF to -1 to avoid such test failure.
