+Subject: [PATCH 2/9] Fix: signal: Remove SEND_SIG_FORCED (v4.20)
+
+See upstream commit :
+
+  commit 4ff4c31a6e85f4c49fbeebeaa28018d002884b5a
+  Author: Eric W. Biederman <ebiederm@xmission.com>

+
+    signal: Remove SEND_SIG_FORCED
+
+    There are no more users of SEND_SIG_FORCED so it may be safely removed.
+
+    Remove the definition of SEND_SIG_FORCED, it's use in is_si_special,
+    it's use in TP_STORE_SIGINFO, and it's use in __send_signal as without
+    any users the uses of SEND_SIG_FORCED are now unncessary.
+
+    This makes the code simpler, easier to understand and use.  Users of
+    signal sending functions now no longer need to ask themselves do I
+    need to use SEND_SIG_FORCED.
