Aneesh Kumar K.V 42fe6484c6 net/9p: Handle error in zero copy request correctly for 9p2000.u ... For zero copy request, error will be encoded in the user space buffer. So copy the error code correctly using copy_from_user. Here we use the extra bytes we allocate for zero copy request. If total error details are more than P9_ZC_HDR_SZ - 7 bytes, we return -EFAULT. The patch also avoid a memory allocation in the error path.
