From 3a81a5210b7d33bb6d836b4c4952a54166a336f3 Mon Sep 17 00:00:00 2001 From: Steven Rostedt (Red Hat) Date: Mon, 11 Nov 2013 11:47:06 -0500 Subject: tracing: Add rcu annotation for syscall trace descriptors sparse complains about the enter/exit_sysycall_files[] variables being dereferenced with rcu_dereference_sched(). The fields need to be annotated with __rcu.
