From 4888f9fc03fc7e9c9ef51cb2ac338680b4a2320c Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Wed, 18 Jan 2023 08:44:16 -0800 Subject: nvme-pci: fix timeout request state check [ Upstream commit 1c5842085851f786eba24a39ecd02650ad892064 ] Polling the completion can progress the request state to IDLE, either inline with the completion, or through softirq. Either way, the state may not be COMPLETED, so don't check for that. We only care if the state isn't IN_FLIGHT. This is fixing an issue where the driver aborts an IO that we just completed. Seeing the "aborting" message instead of "polled" is very misleading as to where the timeout problem resides.
