From 92c76dc036e2139226e90851864d3e01e1db5dd8 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Fri, 13 Dec 2013 15:28:57 +0200 Subject: [PATCH] rbd: wire up is_visible() sysfs callback for rbd bus In preparation for single-major device number allocation scheme, wire up attribute_group::is_visible() callback for rbd bus. This allows us to make the new single-major attributes conditional.
