Turns out that lwn article (from December 2005) is out of date. This
article http://lwn.net/Articles/202449/ (from October 2nd 2006)
appears to have a more accurate description of the api change.
struct iovec
{
void __user *iov_base;
__kernel_size_t iov_len;
};
This article http://lwn.net/Articles/170954/ (from Feb 7th 2006) has a
bit more background, and a promise of future API changes.
