Hi,
At this point, all we're awaiting for is formal Acked-by by affected
maintainers.
Andrew, should you eventually pick it up into your tree ? Or perhaps it should
go through Paul McKenney's tree, given that it uses synchronize_sched() ?
The only change since last post is a layout change in the patch changelog, so
I'm not even bumping the patch version (kept at v18).
Thanks,
Mathieu
