Richard Kennedy a59bb6a18c block: ensure jiffies wrap is handled correctly in blk_rq_timed_out_timer ... commit a534dbe96e upstream. blk_rq_timed_out_timer() relied on blk_add_timer() never returning a timer value of zero, but commit 7838c15b8d removed the code that bumped this value when it was zero. Therefore when jiffies is near wrap we could get unlucky & not set the timeout value correctly. This patch uses a flag to indicate that the timeout value was set and so handles jiffies wrap correctly, and it keeps all the logic in one function so should be easier to maintain in the future.
