 II. How does it work?
 
-There are three per-task flags used for that, PF_NOFREEZE, PF_FROZEN
+There are four per-task flags used for that, PF_NOFREEZE, PF_FROZEN, TIF_FREEZE
 and PF_FREEZER_SKIP (the last one is auxiliary).  The tasks that have
 PF_NOFREEZE unset (all user space processes and some kernel threads) are
 regarded as 'freezable' and treated in a special way before the system enters a
 suspend state as well as before a hibernation image is created (in what follows
 we only consider hibernation, but the description also applies to suspend).
 
 Namely, as the first step of the hibernation procedure the function
-freeze_processes() (defined in kernel/power/process.c) is called.  A system-wide
-variable system_freezing_cnt (as opposed to a per-task flag) is used to indicate
-whether the system is to undergo a freezing operation. And freeze_processes()
-sets this variable.  After this, it executes try_to_freeze_tasks() that sends a
-fake signal to all user space processes, and wakes up all the kernel threads.
-All freezable tasks must react to that by calling try_to_freeze(), which
-results in a call to __refrigerator() (defined in kernel/freezer.c), which sets
-the task's PF_FROZEN flag, changes its state to TASK_UNINTERRUPTIBLE and makes
-it loop until PF_FROZEN is cleared for it. Then, we say that the task is
-'frozen' and therefore the set of functions handling this mechanism is referred
-to as 'the freezer' (these functions are defined in kernel/power/process.c,
-kernel/freezer.c & include/linux/freezer.h). User space processes are generally
-frozen before kernel threads.
+freeze_processes() (defined in kernel/power/process.c) is called.  It executes
+try_to_freeze_tasks() that sets TIF_FREEZE for all of the freezable tasks and
+either wakes them up, if they are kernel threads, or sends fake signals to them,
+if they are user space processes.  A task that has TIF_FREEZE set, should react
+to it by calling the function called __refrigerator() (defined in

+the task's TIF_FREEZE flag and makes the task enter __refrigerator() if the

 For user space processes try_to_freeze() is called automatically from the
 signal-handling code, but the freezable kernel threads need to call it
 explicitly in suitable places or use the wait_event_freezable() or
 wait_event_freezable_timeout() macros (defined in include/linux/freezer.h)
-that combine interruptible sleep with checking if the task is to be frozen and

 If a freezable kernel thread fails to call try_to_freeze() after the freezer has

+set TIF_FREEZE for it, the freezing of tasks will fail and the entire
 hibernation operation will be cancelled.  For this reason, freezable kernel
