[PATCH 1/2] sched/debug: fix per-task line continuation for console

2018-03-19 Thread Joe Lawrence
When the SEQ_printf() macro prints to the console, it runs a simple printk() without KERN_CONT "continued" line printing. The result of this is oddly wrapped task info, for example: % echo t > /proc/sysrq-trigger % dmesg ... runnable tasks: ... [ 29.608611] I [ 29.608613]
