Subject: loop: Report EOPNOTSUPP properly
|
|
|
|
Properly plumb out EOPNOTSUPP from loop driver operations, which may
|
|
get returned when for instance a discard operation is attempted but not
|
|
supported by the underlying block device. Before this change, everything
|
|
was reported in the log as an I/O error, which is scary and not
|
|
helpful in debugging.
