A lot of developers debug their code with trace_printk(), and do the "shotgun approach", where they cut and paste trace_printk()s all over their code in several files. Having to now add: #include <linux/trace_printk.h> whenever a trace_printk() is added is going to be a big PITA and slow down all debugging efforts. -- Steve
