Mike Rapoport Date: Wed Nov 30 09:52:01 2016 +0200 isofs: add KERN_CONT to printing of ER records The ER records are printed without explicit log level presuming line continuation until "\n". After the commit 4bcc595ccd8 (printk: reinstate KERN_CONT for printing continuation lines), the ER records are printed a character per line. Adding KERN_CONT to appropriate printk statements restores the printout behavior.
