From 91561d4ecb755f056f8ff04f9dcaec210140e55c Mon Sep 17 00:00:00 2001 From: Chao Gao Date: Fri, 15 Jul 2022 18:45:33 +0800 Subject: swiotlb: remove unused fields in io_tlb_mem Commit 20347fca71a3 ("swiotlb: split up the global swiotlb lock") splits io_tlb_mem into multiple areas. Each area has its own lock and index. The global ones are not used so remove them.
