Hi Hannes, Here is v2 of Ben's approach to fixing the inability to reload a multipath table that includes failed paths. I've staged it in linux-dm.git's 'for-next' branch. But I wanted to send this v2 out to verify this approach works for you. This approach is focused on allowing failed paths to be pushed down in a multipath table. It does _not_ allow non-existent devices to be listed in an mpath table like your patchset did. So the aggressive dev_loss_tmo case isn't covered... but Ben said that case is already handled by multipathd getting a change event and pushing the table down without the removed SCSI device(s). Thoughts?
