From 7ee329655189f32f0c17e0bad60c23a69b003e9e Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 13 Sep 2018 16:39:58 -0400 Subject: [PATCH] kill TIOCSER[SG]WILD the only user is very old setserial rc script and even that (as far back as MCC Interim, AFAICS) doesn't actually fail - just gives one message during the boot ("Cannot scan for wild interrupts") and proceeds past that just fine.
