Some of neil brown's nfsd patches available here:
It would be worth applying and testing in rawhide or the public beta, whenever
thats coming out.
Specifically he has cleaned up the smp support in nfs and he claims that full
tcp support is working in the nfs server side.
These would be big improvements for a lot of users and worth the patches.
Neil announced these patches here:
Ben applied them, or at least I saw the CVS log.
Worth checking rawhide, I think.
We have applied probably everything of this that is appropriate. Please open
bugs for specific issues.
