patches/lede/0035-base-files-upgrade-don-t-loop-forever-trying-to-kill-processes.patch

+From: Matthias Schiffer <mschiffer@universe-factory.net>
+Date: Thu, 13 Jul 2017 00:19:32 +0200
+Subject: base-files: upgrade: don't loop forever trying to kill processes
+
+When processes don't die on SIGKILL (usually because of kernel bugs), it's
+better to give up instead of looping forever.
+
+upgraded will trigger a reboot in this case (and if this fails, a hardware
+watchdog will eventually time out and reset the system, if present).
