The code is using many fields of struct page in new ways. This is key information for anyone to effectively review the code. So please carefully document (within the code itself) the ways in which the various page fields are used: semantic meaning of the overload, relationships between them, any locking rules or assumptions. Ditto any other data structures. This code should be reviewed very carefully by others so please implement it with that intention. It appears that a pile of dead code will be generated if CPU hotplug is disabled. (That's if it compiles at all!). Please take a look at users of hotcpu_notifier() - this facility cunningly causes all the hotplug code to vanish from vmlinux if it is unneeded. afacit this code should be added to core mm/. Addition of code like this to core mm/ will be fiercely resisted on principle! Hence the (currently missing) justifications for adding it had best be good ones. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
