       The arguments are:

       vp  The vnode that the buffer is for.

       bp  The buffer to be read or written.

       This call either reads or writes data from a file, depending on the value of bp->b_io.bio_cmd.

       The call may block.

       setting b_error to the appropriate errno value.
