#     Merge tag 'for-linus-20180825' of git://git.kernel.dk/linux-block
#     
#     Pull block fixes from Jens Axboe:
#      "A few small fixes for this merge window:
#     
#        - Locking imbalance fix for bcache (Shan Hai)
#     
#        - A few small fixes for wbt. One is a cleanup/prep, one is a fix for
#          an existing issue, and the last two are fixes for changes that went
#          into this merge window (me)"
#     
#     * tag 'for-linus-20180825' of git://git.kernel.dk/linux-block:
#       blk-wbt: don't maintain inflight counts if disabled
#       blk-wbt: fix has-sleeper queueing check
#       blk-wbt: use wq_has_sleeper() for wq active check
#       blk-wbt: move disable check into get_limit()
#       bcache: release dc->writeback_lock properly in bch_writeback_thread()
