From 4621c1768ef5d12171cca2aa1473595ecb9f1c9e Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Wed, 21 Nov 2012 11:21:19 +0530 Subject: virtio-rng: remove extra request for entropy If we got fewer bytes from the backend than requested, don't poke the backend for more bytes; the guest will ask for more (or if the guest has already asked for more, the backend knows about it via handle_input()).
