Subject[PATCHSET pm-freezer] freezer: fixes & simplifications
Date
Hello,

These six patches are fixes and simplifications for the recent freezer
changes. The first four have been posted twice. Changes since the
last posting[L] are

* freezer->state setting bug fix updated per Matt Helsley so that the
actual per-task freeze/thaw operations are always performed.

* fixed a bug caused by forgetting to unlock freezer_lock in "freezer:
restructure __refrigerator()".

* Two patches added. The fifth one is mostly trivial. The sixth a
bit more involved but still shouldn't cause any noticeable
functional difference. This removes the buggy and unused
freezable_with_signal.

Properly tested this time. As hera is still down, no git branch
available at this point. Patch list and diffstat follow.

Thanks.
