From 0c95fdc59640824d7e0b017be295fb912ceef4ab Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 4 Feb 2008 22:28:06 -0800 Subject: [PATCH] iommu sg merging: aacraid: use pci_set_dma_max_seg_size This sets the segment size limit properly via pci_set_dma_max_seg_size and remove blk_queue_max_segment_size because scsi-ml calls it.
