Subject: hrtimer: fix hrtimer_init_sleeper() users
From: Peter Zijlstra <[EMAIL PROTECTED]>
commit 37bb6cb4097e29ffee970065b74499cbf10603a3
Author: Peter Zijlstra <[EMAIL PROTECTED]>
Date: Fri Jan 25 21:08:32 2008 +0100
hrtimer: unlock hrtimer_wakeup
Broke hrtimer_init_sleeper() users. It forgot to fix up the futex caller
of this function to detect the failed queueing and messed up the
do_nanosleep() caller in that it could leak a TASK_INTERRUPTIBLE state.
