2 Freezing of tasks
7 I. What is the freezing of tasks?
10 The freezing of tasks is a mechanism by which user space processes and some
19 The tasks that have PF_NOFREEZE unset (all user space tasks and some kernel
31 wakes up all the kernel threads. All freezable tasks must react to that by
38 tasks are generally frozen before kernel threads.
72 has initiated a freezing operation, the freezing of tasks will fail and the
79 order to wake up each frozen task.  Then, the tasks that have been frozen leave
83 Rationale behind the functions dealing with freezing and thawing of tasks
87   - freezes only userspace tasks
90   - freezes all tasks (including kernel threads) because we can't freeze
91     kernel threads without freezing userspace tasks
96     userspace tasks, or if we want to postpone the thawing of userspace tasks
99   - thaws all tasks (including kernel threads) because we can't thaw userspace
100     tasks without thawing kernel threads
115 Generally speaking, there is a couple of reasons to use the freezing of tasks:
126    tasks that might cause the on-disk filesystems' data and metadata to be
135    Then, after the memory for the image has been freed, we don't want tasks
144    example, be troublesome and without the freezing of tasks we would need some
147 Although Linus Torvalds doesn't like the freezing of tasks, he said this in one
150 "RJW:> Why we freeze tasks at all or why we freeze kernel threads?
171 4. Another reason for freezing tasks is to prevent user space processes from
176    is quite difficult to achieve without the freezing of tasks.  Consider,
182 V. Are there any problems related to the freezing of tasks?
208 There are also problems that the freezing of tasks tends to expose, although
212 at this point.  So, seemingly, the failure is due to the freezing of tasks.
215 request_firmware() will fail regardless of whether or not the freezing of tasks
217 tasks, since it generally exists anyway.
