[PATCH 5/9] nvme/pci: add known admin effects to augument admin effects log page

From: Maxim Levitsky
Date: Tue Mar 19 2019 - 10:42:41 EST


Add known admin effects even if hardware has known admin effects page,
since hardware can't be ever trusted to report sane values.
(on my Intel DC P3700, it reports no side effects for namespace format)
