Can Guo 0339420081 block: pm: Fix possible unbalanced nr_pending ... When someone calls blk_get_request() and blk_put_request() without invoking blk_execute_rq() in between, nr_pending will be unbalanced. Fix this by adding a flag, namely the RQF_PM_ADDED, to track the usage of nr_pending, so that blk_pm_put_request() won't touch nr_pending if the flag is not set. Extra care should be given to blk_pm_requeue_request(), because blk-flush.c inserts flush requests into queue without calling blk_pm_add_request(), if the flush requests get requeued by LLD, blk_pm_requeue_request() should anyways decrease nr_pending in this situation to keep it balanced.
