+Subject: locking/lockdep: Delete unnecesary #include
+Forwarded: https://lore.kernel.org/lkml/20180828203315.GD18030@decadent.org.uk/T/#u
+
+Commit c3bc8fd637a9 ("tracing: Centralize preemptirq tracepoints and u
+nify their usage") added the inclusion of <trace/events/preemptirq.h>.
+liblockdep doesn't have a stub version of that header so now fails to
+build.
+
+However, commit bff1b208a5d1 ("tracing: Partial revert of "tracing:
+Centralize preemptirq tracepoints and unify their usage"") removed the
+use of functions declared in that header.  So delete the #include.
+
+Fixes: c3bc8fd637a9 ("tracing: Centralize preemptirq tracepoints ...")
+Fixes: bff1b208a5d1 ("tracing: Partial revert of "tracing: Centralize ...")
