Subject: [PATCH 2/5] 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.
