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

68 Rationale behind the functions dealing with freezing and thawing of tasks:
76 kernel threads without freezing userspace tasks
97 Generally speaking, there is a couple of reasons to use the freezing of tasks:
117 additional memory and we prevent them from doing that by freezing them earlier.
125 example, be troublesome and without the freezing of tasks we would need some
