Subject: rate-submit: remove code that can never be executed
X-Git-Tag: fio-3.12~19^2
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=8db390cd9131caec46d252dee39a2a511735283c;hp=3d6a6f045d24b281ff94ea71c44a637f6d8f0f9e

rate-submit: remove code that can never be executed

The do-while loop above can only be exited when ret != FIO_Q_BUSY. So
the if (ret == FIO_Q_BUSY) branch will never be taken.
