From 7e273e3b41e32716dc122b293b5f15635af495ff Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 10 Oct 2011 01:08:02 -0700 Subject: udf: Promote some debugging messages to udf_error If there is a problem with a scratched disc or loader, it's valuable to know which error occurred. Convert some debug messages to udf_error, neaten those messages too. Add the calculated tag checksum and the read checksum to error message. Make udf_error a public function and move the logging prototypes together.
