Hello, Rafael.
This is pull request for the following pending patches[ets].
[1] freezer: fix various bugs and simplify implementation, take#2 [2] usb_storage: don't use set_freezable_with_signal() [3] freezer: kill unused set_freezable_with_signal() [4] freezer: fix wait_event_freezable/__thaw_task races
The patches are available in the git repository at:

Oleg Nesterov (1): freezer: fix wait_event_freezable/__thaw_task races
Tejun Heo (22): freezer: fix current->state restoration race in refrigerator() freezer: don't unnecessarily set PF_NOFREEZE explicitly freezer: unexport refrigerator() and update try_to_freeze() slightly freezer: implement and use kthread_freezable_should_stop() freezer: rename thaw_process() to __thaw_task() and simplify the implementation freezer: remove racy clear_freeze_flag() and set PF_NOFREEZE on dead tasks freezer: don't distinguish nosig tasks on thaw freezer: use dedicated lock instead of task_lock() + memory barrier freezer: make freezing indicate freeze condition in effect freezer: test freezable conditions while holding freezer_lock freezer: kill PF_FREEZING freezer: clean up freeze_processes() failure path cgroup_freezer: prepare for removal of TIF_FREEZE freezer: make freezing() test freeze conditions in effect instead of TIF_FREEZE freezer: remove now unused TIF_FREEZE freezer: remove should_send_signal() and update frozen() freezer: fix set_freezable[_with_signal]() race freezer: restructure __refrigerator() freezer: use lock_task_sighand() in fake_signal_wake_up() freezer: remove unused @sig_only from freeze_task() usb_storage: don't use set_freezable_with_signal() freezer: kill unused set_freezable_with_signal()
