10 The freezing of tasks is a mechanism by which user space processes and some
27 whether the system is to undergo a freezing operation. And freeze_processes()

81 kernel threads without freezing userspace tasks
104 Generally speaking, there is a couple of reasons to use the freezing of tasks:
126 freezing them earlier. [Of course, this also means that device drivers
