    That sounds like a bug in the scsi code, doesn't it?

    Is this fixed somewhere?

    I don't want to paper over bugs like this by changing the sysfs core.
    We went through this a lot years ago when scsi changed to use the driver
    core, and I thought we had fixed all of these types of errors properly.

    So, any chance to fix these properly as well?
