When enable CONFIG_PREEMPT_RT, verifier will reject bpf_timer with returning -EOPNOTSUPP. Therefore, skip test cases when errno is EOPNOTSUPP. cd tools/testing/selftests/bpf ./test_progs -t timer 125 free_timer:SKIP 456 timer:SKIP 457/1 timer_crash/array:SKIP 457/2 timer_crash/hash:SKIP 457 timer_crash:SKIP 458 timer_lockup:SKIP 459 timer_mim:SKIP Summary: 5/0 PASSED, 6 SKIPPED, 0 FAILED Signed-off-by: Leon Hwang <leon.hwang@linux.dev> Link: https://lore.kernel.org/r/20250910125740.52172-3-leon.hwang@linux.dev Signed-off-by: Alexei Starovoitov <ast@kernel.org>
