Subject: [PATCH 05/11] mm,tlb: turn dummy defines into inline functions
Date: Wed, 1 Aug 2018 06:02:49 -0400 [thread overview]
Message-ID: <20180801100255.4278-6-riel@surriel.com> (raw)
In-Reply-To: <20180801100255.4278-1-riel@surriel.com>
Turn the dummy tlb_flush_remove_tables* defines into inline functions,
in order to get compiler type checking, etc.
