From c3bfe7176c035a0a2c70bc79180fb13a6c57142a Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Mon, 8 Jul 2013 17:26:25 -0400 Subject: NVMe: Namespace IDs are unsigned The 'Number of Namespaces' read from the device was being treated as signed, which would cause us to not scan any namespaces for a device with more than 2 billion namespaces. That led to noticing that the namespace ID was also being treated as signed, which could lead to the result from NVME_IOCTL_ID being treated as an error code.
