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
126 freezing them earlier. [Of course, this also means that device drivers
150 freezing user threads I don't find really objectionable."
171 V. Are there any problems related to the freezing of tasks?
213 VI. Are there any precautions to be taken to prevent freezing failures?
