Subject: [PATCH 09/40] tracing: move __start_ftrace_events and __stop_ftrace_events to header file
Date: Wed, 23 Jun 2010 20:02:50 +1000 [thread overview]
Message-ID: <1277287401-28571-10-git-send-email-imunsie@au1.ibm.com> (raw)
In-Reply-To: <1277287401-28571-1-git-send-email-imunsie@au1.ibm.com>
From: Jason Baron <jbaron@redhat.com>
trace_syscalls.c uses __start_ftrace_events and __stop_ftrace_events in order
to prune compat syscall ftrace events that are not referenced by the compat
syscall table. So move the 'extern' definitions to a common header file.
