Comment 10 for bug 1856871

@thadeu,

To respond your question "What is the exact problem this is causing?"

So far it's not causing much problem, it's pretty harmless, but while running sosreport block plugin (which most Canonical customer uses) it may lead to output "blk" error to the stderr and save syslog || kern.log.

As an fyi, we are re-working the sosreport block plugin upstream to prevent to query unused disk, but still, while I agree with your EIO statement, I don't think a detached loop device should behave differently from a "never" detached loop device, if there current state is "unused" unless I missed something. IMHO they should produce consistent behaviour if 'unused' no ?
