git-svnexport

I noticed a git-svnexport, but don't see an easy way to do the more common task ... export a replica (via svn) of a kernel directory whose master copy is in git (no changes come through svn, all changes come through git).

The Samba team (jra and others) use svn and would like me to keep more uptodate the svn branch (which I sync manually now by applying the patches from the kernel git tree by hand) for the two cifs git trees. Basically I need to do something like:

git log fs/cifs save off each of the commits which hit fs/cifs which are not in the svn tree yet patch and "svn checkin" each of the commits to the svn tree

Has anyone done any scripts to --- export -- to an svn tree from part of a git tree? I don't want to go to having my svn tree as the master and import into git from svn.
