             Bug #: 13513
           Summary: undo PR11759 for newer PREEMPT_RT kernels
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
        AssignedTo: systemtap@sourceware.org
        ReportedBy: fche@redhat.com
    Classification: Unclassified


Newer CONFIG_PREEMPT_RT kernels don't need this hack to let systemtap
(somewhat) work.  The hack was never that good anyway, so removing it should
make us better rt citizens.

+#if CONFIG_PREEMPT_RT
+static raw_spinlock_t itrace_lock;
+#else
 static spinlock_t itrace_lock;
+#endif
