From 3af8f177faec822e8d616d03e73747fa3fd39228 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Thu, 25 Sep 2014 10:16:59 +1000 Subject: [PATCH] ohci: Split long traces to smaller ones Recent traces rework introduced 2 tracepoints with 13 and 20 arguments. When dtrace backend is selected (--enable-trace-backend=dtrace), compile fails as sys/sdt.h defines DTRACE_PROBE up to DTRACE_PROBE12 only. This splits long tracepoints.
