actually, there's an ifdef that does path_release() instead of dput()
for the linux 2.4 kernels.  i think derek is right about leaking
resource information though.  if i start afs and immediately shutdown
it does work.  if i use it for a while though i cant shutdown cleanly
(although sometimes it will still shutdown)

although looking more closely at the code i suspect that the 
path_release should NOT be conditional and it should always 
occur:
