Subject: [PATCH v2 1/6] um: Remove unused kpte_clear_flush macro
Date: Fri, 16 Aug 2024 17:59:48 +0800 [thread overview]
Message-ID: <20240816095953.638401-2-tiwei.btw@antgroup.com> (raw)
In-Reply-To: <20240816095953.638401-1-tiwei.btw@antgroup.com>
This macro has no users, and __flush_tlb_one doesn't exist either.
