Hi, Patch 1 is just something I came across while debugging an issue, killing old and unused code. Patch 2 fixes an issue with IOCB_HIPRI -> REQ_POLLED, where we always set REQ_NOWAIT as well. We should not be combining these two flags, they are separate properties and it's up to the caller to do the right thing and set one or both as they see fit. -- Jens Axboe
