-- v2: server: Eliminate async_alerted() helper function. server: Eliminate async_unknown_status() helper function. server: Remove "unknown_status" field from struct async. server: Remove "alerted" field from struct async. server: Remove "terminated" field from struct async. server: Remove "signaled" field from struct async. server: Remove "direct_result" field from struct async. server: Signal async unconditionally in async_set_result(). server: Introduce a new async state enum. server: Introduce async_unknown_status() helper to compute the 'unknown_status' flag. server: Introduce async_alerted() helper to compute the 'alerted' flag. server: Introduce async_terminated() helper to compute the 'terminated' flag.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=148557
