From: Song Liu [mailto:[email protected]] Sent: Monday, August 25, 2014 10:26 AM To: Song Liu Cc: Dan Williams; Hannes Reinecke Subject: [PATCH 2/5] SES: generate KOBJ_CHANGE on enclosure attach
From: Dan Williams <[email protected]> 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.
