byte-range locking is implemented in the file system, but it requires a
userspace component (and a userspace cluster stack) in order to work. As far
as I know, SLES11 (via the HA extension) is the only distro currently
shipping all the bits to make it work right.

Since you're building a mainline kernel, I don't really know what distro
you're on.
