The patch titled
devpts: move common mknod_ptmx() calls into caller
has been removed from the -mm tree. Its filename was
devpts-move-common-mknod_ptmx-calls-into-caller.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: devpts: move common mknod_ptmx() calls into caller
From: Sukadev Bhattiprolu <sukadev@xxxxxxxxxxxxxxxxxx>
We create 'ptmx' node in both single-instance and multiple-instance
mounts. So devpts_get_sb() can call mknod_ptmx() once rather than have
both modes calling mknod_ptmx() separately.
