Subject: [PATCH v3 0/3] kconfig: Add transitional symbol attribute for migration support
Date: Tue, 23 Sep 2025 14:34:16 -0700 [thread overview]
Message-ID: <20250923213120.make.332-kees@kernel.org> (raw)
Hi,
Add the new "transitional" keyword to kconfig and use it to rename
CONFIG_CFI_CLANG to CONFIG_CFI.
v3: use Vegard's approach, add selftests
v2: https://lore.kernel.org/lkml/20250830020109.it.598-kees@kernel.org/
v1: https://lore.kernel.org/all/20250830014438.work.682-kees@kernel.org/
