    Note that this is not an equivalent change: first variant always prints 
the message, while pr_debug() only does this if DEBUG is #define'd or dynamic 
debugging is enabled.

    This should probably be in a separate patch.

    You should also adjust indentation of the continuation line. Same comment 
to the code furhter below...

    It would have been good if you moved the string literal to the preceding 
line. Same comment to the below code.
