Subject: ftrace: Output REC->var instead of __entry->var for trace format
X-Git-Tag: v2.6.30-rc2~75^2~4
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0462b5664b2bda5a18fef7efb5bb32ce36590c1a;p=karo-tx-linux.git

ftrace: Output REC->var instead of __entry->var for trace format

print fmt: "irq=%d return=%s", __entry->irq, __entry->ret ? \"handled\" : \"unhandled\"

"__entry" should be convert to "REC" by __stringify() macro.
