From 34ef61b1fa6172e994e441f1f0241dc53a75bd5f Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Sat, 2 Mar 2013 16:49:10 -0500 Subject: [PATCH] tracing: Add __per_cpu annotation to trace array percpu data pointer With the conversion of the data array to per cpu, sparse now complains about the use of per_cpu_ptr() on the variable. But The variable is allocated with alloc_percpu() and is fine to use. But since the structure that contains the data variable does not annotate it as such, sparse gives out a lot of false warnings.
