Subject: [PATCH] udiskslinuxblock: Only permit ATA Secure Erase during
Format() on a whole block device
ATA Secure Erase requested as an option to the Format() method call used
to perform the actual erase on a whole drive object it looked up. When
Format() was called on a partition, this led to data loss on a whole drive.
This commit adds a safeguard to check that the Format() is requested
on a whole block device.
Severity of this issue was slightly lowered by a failure to submit
the ATA Secure erase command in case some filesystem was mounted
at that point.
