From ded45505dbfdcaf1e49ae0349e5dafb59c9efbe5 Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Wed, 6 Jun 2018 08:13:06 -0600 Subject: nvme-pci: queue creation fixes We've been ignoring NVMe error status on queue creations. Fortunately they are uncommon, but we should handle these anyway. This patch adds checks for the a positive error return value that indicates an NVMe status. If we do see a negative return, the controller isn't usable, so this patch returns immediately in since we can't unwind that failure.
