[PATCH] Btrfs: kill unreachable code in push_node_left

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We had the following code in push_node_left:

	x = min(y, x);
        if (x < y) {
		/* confusing comment here */
		...
	}

That if's condition can't become true, so just kill the entire block. Plus:
no one will ever need to worry about the removed confusing comment.
