I've posted a "technology preview" release of my patch set for 2.4.20 at 
oss.oracle.com:

   http://oss.oracle.com/~cel/linux-2.4/2.4.20-rc4/

This is a preview to allow developers who use the patch set to learn 
about changes to the 2.6.20 version of the patch set before it is released.

This release includes:

o  the final patches in the RPC transport switch series
o  support for rpcbind protocol versions 3 and 4
o  RPC client support for IPv6
o  some support for IPv6 in the NFS client and RPC server
o  elimination of the global kernel lock from the NFS client
o  miscellaneous bug fixes and clean ups

The release notes have more details.
