From ac5ccdba3a1659b3517e7e99ef7d35a6a2d77cf4 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Thu, 19 Jun 2014 21:22:56 +0300 Subject: iovec: move memcpy_from/toiovecend to lib/iovec.c ERROR: "memcpy_fromiovecend" [drivers/vhost/vhost_scsi.ko] undefined! commit 9f977ef7b671f6169eca78bf40f230fe84b7c7e5 vhost-scsi: Include prot_bytes into expected data transfer length in target-pending makes drivers/vhost/scsi.c call memcpy_fromiovecend(). This function is not available when CONFIG_NET is not enabled. socket.h already includes uio.h, so no callers need updating. Reported-by: Randy Dunlap Cc: Stephen Rothwell Cc: "David S.
