Thanks. That's where I was looking. Device mapper likes to use uevents and they are all over place. However I found drivers/md/md.c that uses uevents in same way as my proof of concept patch. I've posted my patch to LKML to see what they think about it. In case anyone is interested here's the link https://patchwork.kernel.org/patch/2172791/ Milos
