If so, please tell me, what is the first confirmed kernel version, which 
supports this. Or at least, is it available on Kernel 3.5.

I know, that it is possible to assign nodatacow attribute to files with 
"chattr +C <filename>", if the file has zero length.

Thank you

I'm working on per-subvolume mount options that would make possible to
do what you ask about.
