Thanks, how cool!
I feared already that this feature is dead, glad to hear it is not :)

When compiling e2fsprogs from git, I get:
> e4defrag.c:388: error: conflicting types for ‘fallocate’
> /usr/include/bits/fcntl.h:240: note: previous declaration of ‘fallocate’ was here
> make: *** [e4defrag.o] Error 1

I had to comment out fallocate in fcntl.h, no idea who is wrong here.

Thanks again, Clemens
