| |
As part of recent stabilizing of the proxy-execution series, I've seen a number of issues from the test-ww_mutex module.
This is great for shaking out problems in the patches, but in some cases it seems the patch series has made it easier to uncover problems in the test-ww_mutex stress tests.
So this patch series provides a few fixes that I've come up with in testing with qemu using large cpu counts.
Feedback would be greatly appreciated!
thanks -john
