I tried to use a single opcode for files/buffers but ran into an
issue since work_flags is different for files/buffers. This should
be ok for the most part since req->work.flags is ultimately examined;
however, there are place where io_op_defs[opcode].work_flags is examined
directly, and I wasn't sure what would the best way to handle that.
