It's also discard_read/discard_write. scsi_debug has a similar option, fake_rw, which discards both read and write data. > And scsi_ram has a different data storage model from scsi_debug -- > scsi_debug simulates an arbitrarily sized disc by wrapping around some > small (virtually) contiguous allocation of pages; scsi_ram actually > allocates the amount of ram that it's told to.

IIRC, if virtual_gb option is set to zero, scsi_debug allocates the amount of ram that it's told to. > I'm in no way opposed to merging the two; it's a question of whether > Doug will mind me doing some surgery on his driver. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
