-Subject: [PATCH 4/4] Fix: kretprobe: null ptr deref on session destroy
-
-The `filter_bytecode_runtime_head` list is currently not initialized for
-the return event of the kretprobe. This caused a kernel null ptr
-dereference when destroying a session. It can reproduced with the
-following commands:
-
-  lttng create
-  lttng enable-event -k --function=lttng_test_filter_event_write my_event
-  lttng start
-  lttng stop
-  lttng destroy
-
-Upstream-status: backport
