John Dyson 8b612c4b4a This commit is the embodiment of some VFS read clustering improvements.
Firstly, now our read-ahead clustering is on a file descriptor basis and not
on a per-vnode basis.  This will allow multiple processes reading the
same file to take advantage of read-ahead clustering.  Secondly, there
previously was a problem with large reads still using the ramp-up
algorithm.  Of course, that was bogus, and now we read the entire
"chunk" off of the disk in one operation.   The read-ahead clustering
algorithm should use less CPU than the previous also (I hope :-)).

NOTE:  THAT LKMS MUST BE REBUILT!!!
