Hi all, here is a patchset to implement 'low water mark' disk events. This event corresponds to a TP Soft Threshold Reached UA for SCSI or a 'low watermark' event for dm-thin. It utilises the existing 'disk event' infrastructure from the blocklayer to send out the events via udev. And it also cleans up the ambiguous MEDIA_CHANGE event handling from libata, where AN (asynchronous notification) events would be signalled via SCSI events, and polled MEDIA_CHANGE events would be signalled via disk events. And I've added thin provisioning support to brd, too, to have a simple testbed for the new low water mark disk event. As usual, comments and reviews are welcome.
