Subject: [PATCH bpf-next 1/3] libbpf: fix up global symbol counting logic
Date: Wed, 18 May 2022 11:59:13 -0700 [thread overview]
Message-ID: <20220518185915.3529475-2-andrii@kernel.org> (raw)
In-Reply-To: <20220518185915.3529475-1-andrii@kernel.org>
Add the same negative ABS filter that we use in VERSIONED_SYM_COUNT to
filter out ABS symbols like LIBBPF_0.8.0.
