Jens Axboe 149a051f82 as-iosched: fix double locking bug in as_merged_requests() ... If the two requests belong to the same io context, we will attempt to lock the same lock twice. But swapping contexts is pointless in that case, so just check for rioc == nioc before doing the double lock and copy.
