Current code sets size0 to 0 at the start of work request posting functions and then handles size0 == 0 specially within the loop over work requests. Change this so size0 is set along with f0 the first time through the loop (when nreq == 0). This makes the code easier to understand by making it clearer that f0 and size0 are always initialized if nreq != 0 without having to know that size0 == 0 implies nreq == 0. Also annotate size0 with uninitialized_var() so that this doesn't introduce a new compiler warning. Signed-off-by: Roland Dreier <rolandd@cisco.com> |
