Re: [PATCH 0/4] notify userspace of offline->running transitions (v2)

Hey,

Would it be ok to still merge patches 1 - 3? I think they are still
useful on their own. They fix that issue where during fast io
fail/replacement_timeout failures IO is failed, but the scsi_device
state indicates the devices are still running.

It seems Hannes was ok with them right?

Drop patch 4 since we all seemed to agree we will do it a different way.
