(...as hinted at here: > http://www.redhat.com/archives/dm-devel/2012-February/msg00041.html) Most of the support patches went in to mainline several years ago so this is probably due to later changes in md/ - I'd have to take a look at the errors to see what's failing for you. That said, the original patch is somewhat abandoned at this stage. I've not done any work on it beyond helping folks get it applied and built for quite a few years and the block mapping approach it uses was rejected on LKML without VFS changes to make it safe (it operates behind the file system's back). I did start work last year on a revised dm-loop that was a refactoring of and thin wrapper around the existing drivers/block loop driver but this isn't published anywhere at the moment. It could probably be cleaned up and put somewhere without too much work but it's not something I'm working on regularly at the moment. I know Mikulas was also interested in reviving dm-loop and we had some discussions at Devconf in Brno earlier in the year but nothing has happened since.
