Sagi Grimberg dd0107a089 IB/iser: set block queue_virt_boundary ... The block layer can reliably guarantee that SG lists won't contain gaps (page unaligned) if a driver set the queue virt_boundary. With this setting the block layer will: - refuse merges if bios are not aligned to the virtual boundary - split bios/requests that are not aligned to the virtual boundary - or, bounce buffer SG_IOs that are not aligned to the virtual boundary Since iser is working in 4K page size, set the virt_boundary to 4K pages. With this setting, we can now safely remove the bounce buffering logic in iser.
