posix_fallocate on ZFS

Hi,

This has been disabled on ZFS since last November.
And I do understand the rationale on this.

BUT

I've now upgraded some of my HEAD Ceph test systems and they now fail, 
since Ceph uses posix_fallocate() to allocate space for the 
FileStore-journal.

Is there any expectation that this is going to fixed in any near future?
