Subject: [PATCH v2 3/5] selftests/bpf: Use the new NMI_BITS definition
Date: Thu, 1 Oct 2026 10:25:17 +0200 [thread overview]
Message-ID: <20261001082519.16195-4-boqun@kernel.org> (raw)
In-Reply-To: <20261001082519.16195-1-boqun@kernel.org>
The definition of NMI_BITS was out of sync after the introduction of
HAS_SEPARATE_PREEMPT_RESCHED_BITS, hence adjust it.
