{$adjacent}_post_link filter should pass $adjacent variable itself as parameter.

[ankit.gade@…]

{$adjacent}_post_link filter should pass $adjacent variable itself as parameter to the callback function. This will be useful in scenario where I am using same callback function for previous_post_link and next_post_link filters.

If this variable is not passed, I will be unable to determine whether given post is previous or next to current post. Moreover, I will have to write nearly same code twice.

Looks good. The new parameter needs adding to the filter docblock though.
