Thanks for looking into it! Here is what gdb says:
Reading symbols from /opt/kvm/bisect/vmlinux-3.16.0-74665016086615bb+...done. (gdb) l *(scsi_dma_unmap+0x54) 0xffffffff8146a0b4 is in scsi_dma_unmap (drivers/scsi/scsi_lib_dma.c:50). 45 struct device *dev = cmd->device->host->dma_dev; 46 47 dma_unmap_sg(dev, scsi_sglist(cmd), scsi_sg_count(cmd), 48 cmd->sc_data_direction); 49 } 50 } 51 EXPORT_SYMBOL(scsi_dma_unmap);
