I will only fix bugs in the NFS utilities and serious kernel NFS bugs which I can duplcate easily. If you have any kernel NFS server problem, please report it to the Linux kernel mailing list. If it can be reproduced with Linux NFS server and client in less than 5 minutes, you can also send me a copy in addition to sending it to the Linux kernel mailing list. I may take a look when I have time. However I will collect kernel NFS related patches.
Contributions are more than welcome.
The NFS lock only works with lockd. A patch for mknod. A patch for quota. Fix hostname matching for wildcard, subnet and netgroup. Modified mountd to allow clients without IP address to hostname map.
