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

commit ffeb58b
Note that the stap running on -rt kernels is less robust than normal
ones, for reasons yet to be investigated. See bug #13514.
