Subject: target: Use LIST_HEAD()/DEFINE_MUTEX() for static objects
X-Git-Tag: v3.4-rc1~146^2~59
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d0f474e501929acdbd116cca39ef083012f70f25;p=pandora-kernel.git

target: Use LIST_HEAD()/DEFINE_MUTEX() for static objects

Instead of

   static struct list_head foo;
   static struct mutex bar;

   ...

   INIT_LIST_HEAD(&foo);
   mutex_init(&bar);

just do

   static LIST_HEAD(foo);
   static DEFINE_MUTEX(bar);

Also remove some superfluous struct list_head and spinlock_t
initialization calls where the variables are already defined using
macros that initialize them.

This saves a decent amount of compiled code too:

    add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-178 (-178)
    function                                     old     new   delta
    target_core_init_configfs                    898     850     -48
    core_scsi3_emulate_pro_preempt              1742    1683     -59
    iscsi_thread_set_init                        159      88     -71
