From 15a0fbbc8e0d4c135b069c34258fbaebad471dd7 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 30 Dec 2014 14:46:15 -0800 Subject: [PATCH] ses: generate KOBJ_CHANGE on enclosure attach In support of a /dev/disk/by-slot populated with data from the enclosure and ses modules udev needs notification when the new interface files/links are available. Otherwise, any udev rules specified for the disk cannot assume that the enclosure topology has settled.
