Subject: io-wq: don't repeat IO_WQ_BIT_EXIT check by worker
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=769e683715211ad3cbed5908a86b97dd54d60970;p=uclinux-h8%2Flinux.git

io-wq: don't repeat IO_WQ_BIT_EXIT check by worker

io_wqe_worker()'s main loop does check IO_WQ_BIT_EXIT flag, so no need
for a second test_bit at the end as it will immediately jump to the
first check afterwards.
