From 7a81e316866be8053b18fe1dffc663f1ff19bfc3 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 8 Nov 2005 21:35:07 -0800 Subject: [PATCH] [PATCH] re-add TIOCSTART and TIOCSTOP compat_ioctl handlers We don't implement these ioctls, but some architectures define them in the headers. Bash picks them up and issues them frequently. Add compat_ioctl handlers to silence warnings about unhandled copat ioctls.
