[Qemu-devel] [PATCH v5 12/31] vhost: use error_report() instead of fprintf(stderr, ...) |
Date: |
Thu, 21 Jul 2016 12:57:31 +0400 |
From: Marc-André Lureau <address@hidden>
Let's use qemu proper error reporting API, this ensures the error is
reported at the right place (stderr or monitor), with a conventional
format.
