From 154989e45fd8de9bfb52bbd6e5ea763e437e54c5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 22 Nov 2018 16:44:07 +0100 Subject: aio: clear IOCB_HIPRI No one is going to poll for aio (yet), so we must clear the HIPRI flag, as we would otherwise send it down the poll queues, where no one will be polling for completions. Signed-off-by: Christoph Hellwig IOCB_HIPRI, not RWF_HIPRI.
