Subject: [PATCH 2/3] genksyms: remove dead code for ST_TABLE_*
Date: Sat, 16 Jan 2021 08:43:03 +0900 [thread overview]
Message-ID: <20210115234305.87205-2-masahiroy@kernel.org> (raw)
In-Reply-To: <20210115234305.87205-1-masahiroy@kernel.org>
No one sets lexstate to ST_TABLE_*. It is is very old code, and I do
not know what was the plan at that time. Let's remove the dead code.
