Heh, sorry about that, so to sum up the outstanding patches.

for-fixes (current merge window)

 [1] wait_event_freezekillable: use freezer_do_not_count/freezer_count
 [2] freezer: revert 27920651fe "PM / Freezer: Make fake_signal_wake_up() wake TASK_KILLABLE tasks too"

  It would be a good idea to note that the first patch makes thes
  change made by commit 27920651fe and thus reverting is safe.

for-next

 [3] freezer: fix various bugs and simplify implementation, take#2
 [4] usb_storage: don't use set_freezable_with_signal()
 [5] freezer: kill unused set_freezable_with_signal()
 [6] freezer: fix wait_event_freezable/__thaw_task races

All the for-next patches are in the following git branch in the above
order.

Thank you.
