Hi Alex, thanks for your bug report. Sorry for the long delay in replying. Long inbox...
I took a quick look into this. Unfortunately I can't find dm_snapshot.c in either the kernel tree or the evms source code tree, nor anything that looks like it. Do you have any idea where it is? I also took a quick look through the bitkeeper changelogs for 2.4 and 2.6, and can't see anything tagged EVMS since August 2003. So no fun there. Unfortunately thats about as far as I can get without devoting a lot of time to this. If you have any additional info, please send it here as it comes to hand.
