No it hasn't been fixed. ...and no, this is not a problem that only affects NFS: it just happens to give a more noticeable performance impact due to the larger latency of NFS over a 100Mbps link.
I will get round to this, but the general opacity of the current readahead code has been a bit of a put-off in the face of other NFS problems.
Cheers, Trond
