uname usage in internal_errqueue.cc check - Seccomp

[Chenwei]

Hi team,

We are using gRPC with certain seccomp filter, as uname may leak the kernel information, we disallow it from our Seccmop policy.

However, I saw the usage of uname for the check here: https://github.com/grpc/grpc/blob/master/src/core/lib/iomgr/internal_errqueue.cc#L39C5-L42C6 I wonder if it's possible to have some configuration to skip this check as we won't need the errqueue support, thanks.
