The following reply was made to PR kern/136865; it has been noted by GNATS. From: Martin Birgmeier <Martin.Birgmeier@aon.at> To: bug-followup@FreeBSD.org, simon@comsys.ntu-kpi.kiev.ua Cc: Subject: Re: kern/136865: [nfs] [patch] NFS exports atomic and on-the-fly atomic updates Date: Sat, 20 Oct 2012 11:43:17 +0200 Andrey, I'd really like to use this. However, I need to use it with FreeBSD 7.4, 8.2, and 9.0 (and 9.1 in the near future); I tried to backport your changes, but this turned out to be too difficult for me. I believe your work could be more easily adopted (even into the core FreeBSD sources) provided that - patches for all supported branches of FreeBSD were available and - there existed a simple knob in rc.conf where one switches between the old mountd and the new nfse I guess that for the latter you'd also need to introduce some compatibility shims into your kernel changes, such that a single kernel could support both methods. What is your opinion? Regards, Martin p.s. I have seen that just a few days a workaround was committed to suspend the nfs daemons while mountd reloads the exports list, but this is just a stopgap (as mentioned in the commit message). I'd much more prefer nfse.
