Subject: [PATCH 0/2] tracing: Fixes to event_triggers patches found by Fengguang's test bot

Tom,

This is the changes I made to fix the reports that Fengguang's kbuild test bot
found. I folded in your change that fixes the bug with -ENODEV used in kernel.h.

Paul,

I've Cc'd you because the second patch is fixing up RCU notation. The filter
is protect by rcu_sched, and the first hunk of the patch is performed
within a rcu_read_lock_sched(), and the second hunk is done on the write
side. The tmp variable holds the old value, the value is updated, and
then the new value gets updated. I emailed you so that you can verify
that this all works.

Thanks!
