From 5447ed6c968e7270b656afa273c2b79d15d82edd Mon Sep 17 00:00:00 2001 From: Douglas Gilbert Date: Sun, 25 Apr 2010 12:30:23 +0200 Subject: [PATCH] [SCSI] scsi_debug: virtual_gb ignores sector_size In the scsi_debug driver, the virtual_gb option ignores the sector_size, implicitly assuming that is 512 bytes. So if 'virtual_gb=1 sector_size=4096' the result is an 8 GB (virtual) disk.
