From 4959f2de11ca532a120a337429e5576fd283700f Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sat, 19 Dec 2015 20:07:40 +0000 Subject: [PATCH] futex: Remove pointless put_pi_state calls in requeue() In the error handling cases we neither have pi_state nor a reference to it. Remove the pointless code.
