History
Thomas Gleixner aa08027927 futex: Always cleanup owner tid in unlock_pi 
commit 13fbca4c6e upstream.

If the owner died bit is set at futex_unlock_pi, we currently do not
cleanup the user space futex.  So the owner TID of the current owner
(the unlocker) persists.  That's observable inconsistant state,
especially when the ownership of the pi state got transferred.

Clean it up unconditionally.
