Actually, comments from the CR that resulted in vn_path() being unexported 
indicate that filesystems are expected to refer to v_path directly. 
Another CR has been filed to correct the problem; if that is accepted, then 
perhaps a future version of the Solaris patch will undo the removal, 
allowing existing OpenAFS releases to work as long as you skip the broken 
patch version(s).  Of course, I don't speak (or even work) for Sun, so I 
can't make any promises.  In the meantime, the issue is also corrected in 
OpenAFS, so 1.4.2 should not have this particular problem.

Note that Sun doesn't provide guarantees about binary compatibility of the 
VFS interface, and there have been changes in the past.  However, some of 
us have contacts within Sun and we're working to try to establish a more 
formal relationship that will allow the OpenAFS project to receive 
notification when Sun is planning changes to this interface.
