The patch titled
loop: use unlocked_ioctl
has been removed from the -mm tree. Its filename was
loop-use-unlocked_ioctl.patch
This patch was dropped because it isn't in the present -mm lineup
------------------------------------------------------
Subject: loop: use unlocked_ioctl
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
The last lock_kernel() has disappeared from loop.c. Switch it over to using
unlocked_ioctl.
