Re: [libvirt] [PATCH] BZ1072677: Avoid freeing of 0 file descriptor

Indeed: $ git grep memset.*1 src/conf/domain_conf.c: memset(max_idx, -1, sizeof(max_idx)); src/qemu/qemu_command.c: memset(tapfd, -1, tapfdSize * sizeof(tapfd[0])); src/qemu/qemu_command.c: memset(vhostfd, -1, vhostfdSize * sizeof(vhostfd[0])); So let's just copy that convention, instead of adding a new macro. ACK to the qemu_hotplug fixes if you switch to raw memset.
