+
+  random: remove unused tracepoints
+
+  These explicit tracepoints aren't really used and show sign of aging.
+  It's work to keep these up to date, and before I attempted to keep them
+  up to date, they weren't up to date, which indicates that they're not
+  really used. These days there are better ways of introspecting anyway.

+Subject: [PATCH] fix: sched/tracing: Append prev_state to tp args instead
+ (v5.18)
+
+See upstream commit :
+
+  commit 9c2136be0878c88c53dea26943ce40bb03ad8d8d
+  Author: Delyan Kratunov <delyank@fb.com>
+  Date:   Wed May 11 18:28:36 2022 +0000
+
+    sched/tracing: Append prev_state to tp args instead
+
+    Commit fa2c3254d7cf (sched/tracing: Don't re-read p->state when emitting
+    sched_switch event, 2022-01-20) added a new prev_state argument to the
+    sched_switch tracepoint, before the prev task_struct pointer.
+
+    This reordering of arguments broke BPF programs that use the raw
+    tracepoint (e.g. tp_btf programs). The type of the second argument has
+    changed and existing programs that assume a task_struct* argument
+    (e.g. for bpf_task_storage access) will now fail to verify.
+
+    If we instead append the new argument to the end, all existing programs
+    would continue to work and can conditionally extract the prev_state
+    argument on supported kernel versions.
+
