Currently, the maximum amount of RAM that scsi_debug can actually allocate is 4GB. This patchset increase it to 2TB. Here's an example, scsi_debug allocates 6GB ram and exports it as if it were 6GB disk. fujita@rose:/sys/bus/pseudo/drivers/scsi_debug$ cat virtual_gb 0 fujita@rose:/sys/bus/pseudo/drivers/scsi_debug$ cat dev_size_mb 6144 scsi3 : scsi_debug, version 1.81 [20070104], dev_size_mb=6144, opts=0x0 scsi 3:0:0:0: Direct-Access Linux scsi_debug 0004 PQ: 0 ANSI: 5 sd 3:0:0:0: [sdc] 12582912 512-byte hardware sectors (6442 MB) This patchset also include minor cleanup.
