Subject[PATCH 0/5 v4]Kernel Access to Ftrace instances.
In addition to patches introduced by commit f45d1225adb0 "tracing: Kernel
access to Ftrace instances") we also need the following patches to reliably
access ftrace instances from other kernel modules or components.

This version addresses the review comments/suggestions received for v3.

Please review the patches that follow.

Divya Indi (5):
tracing: Declare newly exported APIs in include/linux/trace.h
tracing: Verify if trace array exists before destroying it.
tracing: Adding NULL checks
tracing: Handle the trace array ref counter in new functions
tracing: New functions for kernel access to Ftrace instances
