Subject: [PATCH 3/3] kbuild: re-enable KCSAN for autogenerated *.mod.c intermediaries
Date: Thu, 14 Nov 2024 08:45:23 +0900	[thread overview]
Message-ID: <20241113234526.402738-4-masahiroy@kernel.org> (raw)
In-Reply-To: <20241113234526.402738-1-masahiroy@kernel.org>

This reverts commit 54babdc0343f ("kbuild: Disable KCSAN for
autogenerated *.mod.c intermediaries").

Now that objtool is enabled for *.mod.c, there is no need to filter
out CFLAGS_KCSAN.

I no longer see "Unpatched return thunk in use. This should not happen!"
error with KCSAN when loading a module.
