Subject: [PATCH -mm 0/3] Freezer: Use wait queue instead of busy looping

Hi,

The patches in the next three messages do the following:
* make the freezer a bit more verbose
* make try_to_freeze_tasks() go to sleep while waiting for tasks to enter
  the refrigerator instead of busy looping
* make try_to_freeze_tasks() measure the time of freezing, regardless of
  whether or not it is successful

Greetings,
Rafael
