I am talking about this line of code
<link rel="alternate" type="application/rss+xml" title="example.com » Comments Feed" href="http://example.com/comments/feed/" />
I have tried adding a remove action hook manually in template's functions.php
But it doesn't remove it.
I have tried wordpress head cleaner plugin unfortunately it also couldn't remove it.
At last I have edited wp-includes/default-filters.php and commented out
add_action( 'wp_head', 'feed_links_extra',3);
My comment feed links are still there. I prefer functions.php modification or plugins other than modifying the core files.
I have tried disabling all the plugins and gone back to default theme but looks like the solution is not plugin or theme dependent. Unfortunately nothing works! I am using wordpress 3.2.1
