Hi,
Here's an updated version of the pcpu rwsem writer wait/wake changes with the abstractions wanted by Oleg. Patch 1 adds rcuwait (for a lack of better name), and patch 2 trivially makes use of it.
Has survived torture testing, which is actually very handy in this case particularly dealing with equal amount of reader and writer threads.
Thanks.
