What would you suggest I read? I looked in include/linux/freezer.h and didn't see any explanations. I found one Documenation file, power/kernel_threads.txt, that explained the interaction of freezing and kernel threads. I looked in the comments for various 2.6.21-rc6-mm1 freezer* patches, and saw various interesting details. But I couldn't find any documentation telling me what a freezer was, or what a refrigerator is. Did I miss something? -- I won't rest till it's the best ...
