10 The freezing of tasks is a mechanism by which user space processes and some
28 indicate whether the system is to undergo a freezing operation. And
72 has initiated a freezing operation, the freezing of tasks will fail and the
83 Rationale behind the functions dealing with freezing and thawing of tasks
91 kernel threads without freezing userspace tasks
115 Generally speaking, there is a couple of reasons to use the freezing of tasks:
137 freezing them earlier. [Of course, this also means that device drivers
144 example, be troublesome and without the freezing of tasks we would need some
