Re: [PATCH 09/44] new iov_iter flavour - ITER_UBUF

[David Howells <dhowells@xxxxxxxxxx>]

You need to modify dup_iter() also.  That will go through the:

		return new->iov = kmemdup(new->iov,
				   new->nr_segs * sizeof(struct iovec),
				   flags);

case with a ubuf-class iterators, which will clobber new->ubuf.
