Like I stated in the original post; currently, certain operations scan through a number of blocks in kernel space. I would like to be able to add an off_t to the argument list of said operations, set to VNOVAL by the caller, then initialized by the VOP, and incremented by it on each pass. The VOP will return a new error code (ERETRY) when the pass only partially completed, and the library will iterate.
