Re: [PATCH 1/6] wined3d: Introduce WINED3DUSAGE_MANAGED.

by Fabian Maurer

Hello Matteo, What's the state on this patch series? I've been investigating bug 45279, and this solves it nicely. It's been almost a month since submission, and I'd like to see that in 4.0 - it fixes a bunch of applications. Not sure if that would be suitable during code freeze though. Regards, Fabian Maurer

[PATCH 2/2] ntdll: Use a CS to ensure that RtlWaitOnAddress compares and queues atomically.

by Zebediah Figura

Currently a wake may occur between calling compare_addr() and performing the select request; in that case the thread will never be woken. Prevent this by taking a CS around both operations.
