Subject: [PATCH 10/16] dax: Simplify root read-only definition for the 'resource' attribute
Date: Wed, 06 Nov 2019 19:57:29 -0800	[thread overview]
Message-ID: <157309904959.1582359.7281180042781955506.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)

Rather than update the permission in ->is_visible() set the permission
directly at declaration time.
