[Jens Axboe <axboe@kernel.dk>]

Hi Linus,

- Fix an off-by-one in a BUILD_BUG_ON() check. Not a real issue right
  now as we have plenty of flags left, but could become one. (Hao)

- Fix lockdep issue introduced in this merge window (me)

- Fix a few issues with the worker creation (me, Pavel, Qiang)

- Fix regression with wq_has_sleeper() for IOPOLL (Pavel)

- Timeout link error propagation fix (Pavel)

Please pull!
