Re: [PATCH v8 0/1] MR4372: kernel32: impl sync barrier

[quininer (＠quininer)]

Based on the docs https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-ini... and https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-ent..., i think that `SpinCount` and `Flags` do not affect behavior in this implement and can be safely ignored.

The return value of `EnterSynchronizationBarrier` does not an error, but rather whether it was the last barrier invoked.

I'm not familiar with how `NTSTATUS` should be handled here, do i need to forward it manually in `kernelbase`?

Barrier can only be used once.
