[PATCH] bcache: Use setup_timer and mod_timer

From: Amitoj Kaur Chawla
Date: Thu Jun 30 2016 - 07:45:35 EST


Convert a call to init_timer and accompanying intializations of
the timer's data and function fields to a call to setup_timer.

The Coccinelle semantic patch that fixes one part of this issue
is as follows:
@@
expression t,d,f,e1;
identifier x1;
statement S1;
@@

(
-t.data = d;
|
-t.function = f;
|
-init_timer(&t);
+setup_timer(&t,f,d);
|
-init_timer_on_stack(&t);
+setup_timer_on_stack(&t,f,d);
)
<... when != S1
t.x1 = e1;
...>

Also convert calls to add_timer and intialisation of timer's expire
field to a call to mod_timer which is more compact.
