Subject: [PATCH] re-add TIOCSTART and TIOCSTOP compat_ioctl handlers
Date: Fri, 4 Nov 2005 23:09:52 +0100 [thread overview]
Message-ID: <20051104220951.GA9301@lst.de> (raw)
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.
