[PATCH 0/1] MR10320: win32u/d3dkmt: Close the wait handle with NtClose() in NtGdiDdDDIAcquireKeyedMutex2().

[Conor McCarthy (＠cmccarthy)]

When a waitable handle is created and closed in the server,
close_inproc_sync() must be explicitly called for cache cleanup in ntdll,
but this function is only available in ntdll.
