From 4f8c85272c5e7ea1f2fe15d866835bc6f8fc996f Mon Sep 17 00:00:00 2001 From: Cyril Roelandt Date: Tue, 12 Feb 2013 05:01:53 +0100 Subject: xen: remove redundant NULL check before unregister_and_remove_pcpu(). unregister_and_remove_pcpu on a NULL pointer is a no-op, so the NULL check in sync_pcpu can be removed.
