[Qemu-devel] [PATCH v2 0/5] block: Fix error report for wrong file format

[Stefan Weil]

These patches improve the error report if the file format was
specified explicitly (example: -drive file=myfile,format=qcow2)
and the given format does not match the real format.

They fix those bugs:

https://bugs.launchpad.net/qemu/+bug/1090600

Changes in v2:

* Use error code EMEDIUMTYPE instead of inventing a new one.
* Split modifications in block/vdi.c into 3 separate patches.

I decided to use EMEDIUMTYPE because I think that it matches best
the kind of error which we want to describe here.

EINVAL is too unspecific, and ENOTTY means something completely different,
therefore I did not use one of those suggested values.

Cheers,
Stefan
