NetBSD 7.0 has just introduced these two syscalls. And Linux also has them.
Does FreeBSD have them? Or plan to support them in the future?
FreeBSD does not have them. It doesn't seem especially hard to implement,
though. Do you know any major application already using them?
I see no harm in having the system calls. When I chatted with the authors of
nsd a couple of years ago (they had originally promoted the approach), they
told me they felt it only offered incremental benefit and didn't particularly
recommend that FreeBSD adopt it. However, it would undoubtably see use and
does offer some opportunities for future batching-related performance
operations, so if someone wants to pursue introducing it, do go ahead. Or
just introduce a libc implementation that can be converted to a kernel
implementation later if that is determined to be beneficial. But the nsd
observations don't (currently) lead me to believe that it is critical to do
so.
