bhyve: Register new kevents synchronously.
ClosedPublic

Authored by jhb on May 27 2021, 1:24 PM.

Details

Summary

Change mevent_add*() to synchronously add the new kevent. This
permits reporting event registration failures to the caller and avoids
failing the registration of other, unrelated events queued up in the
same batch.

Perhaps assert that no error occurred, or cast the return value away.

bhyve is pretty consistent about assuming no errors from mutexes, condvars, and once and not using either void casts or assertions of that (e.g. there's a once in block_if.c), so I think this is consistent with the rest of bhyve.
