[PATCH 7/8] mpt3sas: set an unlimited max_segment_size for SAS 3.0 HBAs

2019-06-17 Thread Christoph Hellwig
When using a virt_boundary_mask, as done for NVMe devices attached to mpt3sas controllers we require an unlimited max_segment_size, as the virt boundary merging code assumes that. But we also need to propagate that to the DMA mapping layer to make dma-debug happy. The SCSI layer takes care of
