Michael, Pete and I checked in a bunch of fixes to get pvfs2 kmod to work on recent kernels.. I am not sure if they were checked into pete's osd trunk or to the main CVS head.. Pete? If you are able to build pvfs2 kmod from HEAD without any compile time warnings it should work just fine after loading..there have been a few dcache related bugs that Phil and Sam have nailed down and hence it is probably a good idea to try CVS head anyways. thanks, Murali
