[Qemu-devel] [PATCH v2 3/6] nbd/server: Better error for NBD_OPT_EXPORT_NAME failure

[Eric Blake]

When a client abruptly disconnects before we've finished reading
the name sent with NBD_OPT_EXPORT_NAME, we are better off logging
the failure as EIO (we can't communicate with the client), rather
than EINVAL (the client sent bogus data).
