My project *would* like this added sooner, so I'll work on a revised
patchset that uses netlink instead of uevents, and will also work on a
revision to uevents.txt that talks about KOBJ_CHANGE and when it should
and should not be used, as described by agk, to help out the next person.

netlink might still be overkill for this at this stage, if it's only
making one thread able to monitor multiple devices efficiently.

Let's find out your requirements and see if there's anything different from
the ones we've debated before.

Yeah just like Hannes said, I just want to get dm events for multiple dm devices without burning a thread for each device. After your clarification, netlink seems like the best option and not overkill.

Give me a few days and I can have something for you to review.
