Subject: [PATCH v5.15 v2 3/4] lib/Kconfig.debug: Use CONFIG_PAHOLE_VERSION
Date: Thu, 23 Feb 2023 11:53:50 +0000	[thread overview]
Message-ID: <20230223115351.1241401-4-maennich@google.com> (raw)
In-Reply-To: <20220201205624.652313-1-nathan@kernel.org>

From: Nathan Chancellor <nathan@kernel.org>

[ Upstream commit 6323c81350b73a4569cf52df85f80273faa64071 ]

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.
