[PATCH 0/1] MR9001: ntdll: Introduce a helper to wait on a server-side sync object.

[Rémi Bernon (＠rbernon)]

Some objects like async or completion waits are internal only, and their
sync logic is still a bit complicated as they have various server side
effects. They are only waited on alone, we can keep using server-side
syncs for them.
