Subject: [RFC PATCH 1/4] mm: move tlb_table_flush to tlb_flush_mmu_free
Date: Thu, 26 Jul 2018 00:06:38 +1000	[thread overview]
Message-ID: <20180725140641.30372-2-npiggin@gmail.com> (raw)
In-Reply-To: <20180725140641.30372-1-npiggin@gmail.com>

There is no need to call this from tlb_flush_mmu_tlbonly, it
logically belongs with tlb_flush_mmu_free. This allows some
code consolidation with a subsequent fix.
