Douglas Anderson bbfceba15f kdb: Get rid of confusing diag msg from "rd" if current task has no regs ... If you switch to a sleeping task with the "pid" command and then type "rd", kdb tells you this: No current kdb registers. You may need to select another task diag: -17: Invalid register name The first message makes sense, but not the second. Fix it by just returning 0 after commands accessing the current registers finish if we've already printed the "No current kdb registers" error. While fixing kdb_rd(), change the function to use "if" rather than "ifdef". It cleans the function up a bit and any modern compiler will have no trouble handling still producing good code.
