Most likely smb_revalidate_inode and friends. The client doesn't see the
size change (I believe tail -f looks for a size change ...) so it doesn't
read anything. But when opening for editing the data is checked again and
the changes appear.
It would be possible to compare the code between kernels and fix it in 2.2
also.
