tracker bug to backport 2.6.35-rc1 fixes in 6.0. commit a02c37891a9b2d7ce93f9d09455b4f67c4c23b95 Author: Takuya Yoshikawa <yoshikawa.takuya.co.jp> Date: Thu May 27 19:03:56 2010 +0900 vhost: fix the memory leak which will happen when memory_access_ok fails We need to free newmem when vhost_set_memory() fails to complete.

Tsirkin <mst> commit d3553a52490dcac54f45083f8fa018e26c22e947 Author: Takuya Yoshikawa <yoshikawa.takuya.co.jp> Date: Thu May 27 19:01:58 2010 +0900 vhost-net: fix to check the return value of copy_to/from_user() correctly copy_to/from_user() returns the number of bytes that could not be copied. So we need to check if it is not zero, and in that case, we should return the error number -EFAULT rather than directly return the return value from copy_to/from_user().
