Subject: [PATCH] ftrace: kill global_start_up
Date: Sun, 20 Jul 2014 17:18:14 +0200	[thread overview]
Message-ID: <20140720151814.GA32439@redhat.com> (raw)

global_start_up is read-only and always zero. It seems that 4104d326
"ftrace: Remove global function list and call function directly" simply
forgot to remove this no longer used variable.
