The patch titled
PI-futex: fix timeout race
has been removed from the -mm tree. Its filename is
pi-futex-rt-mutex-core-fix-timeout-race.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
------------------------------------------------------
Subject: PI-futex: fix timeout race
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
The futex code has consequently the same timeout race as generic sleeper
based nanosleep. Call hrtimer_cancel() unconditionally.
