4 I. What is the freezing of tasks?
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()
57 initiated a freezing operation, the freezing of tasks will fail and the entire
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
128 Although Linus Torvalds doesn't like the freezing of tasks, he said this in one
142 freezing user threads I don't find really objectionable."
152 4. Another reason for freezing tasks is to prevent user space processes from
157 to achieve without the freezing of tasks.  Consider, for example, a process
163 V. Are there any problems related to the freezing of tasks?
167 First of all, the freezing of kernel threads may be tricky if they depend one
173 Second, there are the following two problems related to the freezing of user
187 There are also problems that the freezing of tasks tends to expose, although
191 at this point.  So, seemingly, the failure is due to the freezing of tasks.
194 request_firmware() will fail regardless of whether or not the freezing of tasks
195 is used.  Consequently, the problem is not really related to the freezing of
202 VI. Are there any precautions to be taken to prevent freezing failures?
214 that could lead to freezing failures, because if the suspend/hibernate code
218 leading to freezing failure.
221 since they ask the freezer to skip freezing this task, since it is anyway
225 mutex_[un]lock(&pm_mutex). That would prevent freezing failures.
