Subject: [PATCH bpf-next 4/5] lib/Kconfig.debug: Use CONFIG_PAHOLE_VERSION
Date: Tue, 1 Feb 2022 13:56:23 -0700 [thread overview]
Message-ID: <20220201205624.652313-5-nathan@kernel.org> (raw)
In-Reply-To: <20220201205624.652313-1-nathan@kernel.org>
Now that CONFIG_PAHOLE_VERSION exists, use it in the definition of
CONFIG_PAHOLE_HAS_SPLIT_BTF and CONFIG_PAHOLE_HAS_BTF_TAG to reduce the
amount of duplication across the tree.
