The patch titled
pty: prepare for tty->ops changes
has been removed from the -mm tree. Its filename was
pty-prepare-for-tty-ops-changes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: pty: prepare for tty->ops changes
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
We are about to change the tty layer to avoid keeping private copies of all
the methods in each tty. We have to update the pty layer first as it
currently patches the ioctl method according to the tty type. Use multiple
tty operations sets instead.
