The patch titled
Convert drivers/scsi/ch.c to use unlocked_ioctl
has been removed from the -mm tree. Its filename was
convert-drivers-scsi-chc-to-use-unlocked_ioctl.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: Convert drivers/scsi/ch.c to use unlocked_ioctl
From: Mathieu Segaud <mathieu.segaud@xxxxxxxxx>
As of now, compat_ioctl already runs without the BKL, whereas ioctl runs
with the BKL. This patch first converts changer_fops to use a
.unlocked_ioctl member. It applies the same locking rationale than
ch_ioctl_compat() uses to ch_ioctl().
