[PATCH v2 2/2] swiotlb: checking whether swiotlb buffer is full with io_tlb_used

This patch uses io_tlb_used to help check whether swiotlb buffer is full. io_tlb_used is no longer used for only debugfs. It is also used to help optimize swiotlb_tbl_map_single(). Suggested-by: Joe Jin Signed-off-by: Dongli Zhang --- kernel/dma/swiotlb.c | 10 -- 1 file changed, 4
