Pressing Enter twice at this prompt causes patch to skip this incorrectly detected hunk, and all of the actual patches end up being applied correctly, but it's still an unexpected surprise and I had to stop and figure out what was going on. With the way the stable rc patches are usually posted on kernel.org, the patch file would've omitted the commit comments, thus avoiding this problem. -- -Barry K. Nathan
