[PATCH RESEND 2/5] SES: generate KOBJ_CHANGE on enclosure attach

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dan Williams <dan.j.williams@xxxxxxxxx>

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.
