Dfreezing-of-tasks.txt4 I. What is the freezing of tasks?
6 The freezing of tasks is a mechanism by which user space processes and some

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.
