Revision 15e3d5a285ab9283136dba34bbf72886d9146706 authored by Christoph Hellwig on 03 October 2015, 17:16:07 UTC, committed by James Bottomley on 07 October 2015, 17:24:48 UTC
3w controller don't dma map small single SGL entry commands but instead bounce buffer them. Add a helper to identify these commands and don't call scsi_dma_unmap for them. Based on an earlier patch from James Bottomley.
