...pe->nrbufs. (4) The virtio-console driver tries to touch scatterlist structure sgl in sg_init_table(), but the region is out of bound. To avoid the case, a kernel should check whether pipe->nrbufs is empty or not when splice_write is executed in the virtio-console driver.

Hello. I thought rc used to start nfsiod if you set nfs_cilent_enable back years ago. Now, on my 7.1-RELEASE machine, it sets up a couple of sysctls in /etc/rc.d/nfsclient script but not nfsiod. Is nfsiod obsolete by now? It is still on the system; does it still improve nfs performance? Thanks, Hiro
