[PATCH 1/3] scsi_debug: Increase the reported optimal transfer length

2015-12-16 Thread Martin K. Petersen
The OPTIMAL TRANSFER LENGTH reported by scsi_debug is 64 blocks which translates to 32KB with the default logical block size. That's much lower than what real storage devices typically report (256KB to 1MB). Bump the optimal transfer length to 1024 blocks. Signed-off-by: Martin K. Petersen
