moving some code from fs/ufs into fs/base. The benefit of this approach is that fs components that are fundamentally based on posix I/O (and only differ in some non-posix functionality such as setting stripe size, or which hints are being supported) can avoid having to replicate the same code over and over again. First beneficiary is the lustre fs component, but more are to follow soon. Signed-off-by: Edgar Gabriel <egabriel@central.uh.edu>
