Thanks for the links - haven't seen these patches so far (somebody on the list
just mentioned that someone tried to demangle that stuff some time ago). But
good to know that somebody is working on that pagefault_disable() thing.
Do you know what the plans for this series are? So I can base my patches
(might_sleep() checks for might_fault()) on that queue.
David
