Hello, I have been playing with scsi_debug and found that there is no way how to change the minimum_io_size (OPTIMAL TRANSFER LENGTH GRANULARITY reported by VPD 0xb0).
The current module has minimum_io_size always set to physical_block_size. So here comes a small patch which add a new option to this module to be able to set it independently to the physical_block_size. Default behavior is to keep the minimum_io_size equal to the physical_block_size.
