+Subject: [PATCH] selftests/bpf: Fix uprobe consumer test
+
+With newly merged code the uprobe behaviour is slightly different
+and affects uprobe consumer test.
+
+We no longer need to check if the uprobe object is still preserved
+after removing last uretprobe, because it stays as long as there's
+pending/installed uretprobe instance.
+
+This allows to run uretprobe consumers registered 'after' uprobe was
+hit even if previous uretprobe got unregistered before being hit.
+
+The uprobe object will be now removed after the last uprobe ref is
+released and in such case it's held by ri->uprobe (return instance)
+which is released after the uretprobe is hit.
