Hi Rusty, Today's linux-next merge of the virtio tree got a conflict in drivers/char/virtio_console.c between commit 9ba5c80b1aea ("virtio: console: add locking around c_ovq operations") from the rr-fixes tree and commit 6797999d9958 ("virtio_console: use simplified virtqueue accessors") from the virtio tree. I fixed it up (see below) and can carry the fix as necessary (no action is required). -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc drivers/char/virtio_console.c index ce5f3fc,6d59f16..0000000 --- a/drivers/char/virtio_console.c +++ b/drivers/char/virtio_console.c @@@ -570,9 -569,7 +570,9 @@@ static ssize_t __send_control_msg(struc vq = portdev->c_ovq; sg_init_one(sg, &cpkt, sizeof(cpkt)); + + spin_lock(&portdev->c_ovq_lock); - if (virtqueue_add_buf(vq, sg, 1, 0, &cpkt, GFP_ATOMIC) == 0) { + if (virtqueue_add_outbuf(vq, sg, 1, &cpkt, GFP_ATOMIC) == 0) { virtqueue_kick(vq); while (!virtqueue_get_buf(vq, &len)) cpu_relax();
