[Bug runtime/9947] New: lockdep triggered on rawhide with tracepoints

["jistone at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

When running a simple tracepoint test (below), I noticed a lockdep report of a
circular dependency.  This is just potential problem though, as I haven't had
any deadlocks actually manifest.

The report I'm attaching is for i686, but I also reproduced this on x86_64.

# test script:
probe kernel.trace("sched_switch") { exit() }
