nvme: requeue namespace scan on missed AENs

Browse source

[ Upstream commit 9546ad1a9b ]

Scanning for namespaces can take some time, so if the target is
reconfigured while the scan is running we may miss a Attached Namespace
Attribute Changed AEN.

Check if the NVME_AER_NOTICE_NS_CHANGED bit is set once the scan has
finished, and requeue scanning to pick up any missed change.
