Ahh, I see the mistake.

All you need to fix this is to add a new function:

	void
	flushswchainbuf(struct buf *nbp)
	{
		if (nbp->b_bcount) {
			nbp->b_bufsize = nbp->b_bcount;
			if ((nbp->b_flags & B_READ) == 0)
				nbp->b_dirtyend = nbp->b_bcount;
			BUF_KERNPROC(nbp);
			swstrategy(nbp);
		} else {
			biodone(nbp);
		}
	}

And use this instead of flushchainbuf() in swap_pager_strategy().
