strange, I can't seem to find it in 1.5.56 src/venus/fs.c

There is an fs prefetch in Hartmut's OpenAFS+OSD. It stages the 
restoration of a file that is archieved (e.g., on tape) and not available 
from an RxOSD server anymore. Without prefetching such files, the client 
has to wait for the file to be restored upon the first access.
