Re: [PATCH 3/4] ext4: basic bug shield for move_extent_per_page

Applied, thanks.

I added one sanity check:

+	for(bh = head, block_start = 0; bh != head || !block_start;
+	    block++, block_start = block_end, bh = bh->b_this_page) {

  	    ...
		BUG_ON(nr >= MAX_BUF_PER_PAGE);

+		arr[nr++] = bh;
+	}

...just to make sure a corrupted link list on b_this_page can't cause
a on-stack array overrun.
