+Subject: tools/lib/lockdep: Define pr_cont()
+
+lockdep.c now also uses pr_cont(), so we need to implement it in
+liblockdep.
+
+It is currently always used to continue warning lines, so define
+pr_cont() the same as pr_warn().  If this changes, we might need to
+record the last log level in a TLS variable and have pr_cont() check
+that.
