What is the freezing of tasks? 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 137 freezing them earlier. [Of course, this also means that device drivers 161 freezing user threads I don't find really objectionable." 182 V. Are there any problems related to the freezing of tasks? 224 VI. Are there any precautions to be taken to prevent freezing failures? [all …]
