The file system does the prefetch and it prefetches blocks on a per filebasis
(ie /dev/foo asks for "n, n+1, n+2, n+3
/isofs/frob.rpm asks for "n, next block of frob, next but one of frob..."
I think we have exactly the same problem there, and people have
witnessed accesses through the FS fail near the end of the disk with our
install media. To me, it looks like the same behavior.
Any specific bugzilla #'s ?
