+Subject: [PATCH] fuse: Resolve asan bug in during receive event notification
+ (#4019)
+
+The fuse xlator notify function tries to assign data object
+to graph object without checking an event. In case of upcall
+event data object represents upcall object so during access
+of graph object the process is crashed for asan build.
+
+Solution: Access the graph->id only while event is associated
+          specific to fuse xlator
+
+Fixes: #3954
