btrfs-progs 3.18.2 shipped with /usr/include/btrfs/version.h which contains:

$ grin BTRFS_BUILD_VERSION /usr/include/btrfs/version.h 
/usr/include/btrfs/version.h:
   14 : #define BTRFS_BUILD_VERSION "Btrfs v3.18.2"

Do we have a solution to this in master yet?

ping @tianon I suspect Gentoo might have similar issues?

This is a dupe of #11417. 😉
