Mdadm in FC5

[Gregory Maxwell]

I noticed the mdadm in FC5 test 1 is still at 1.11. There have been a
number of important advances in raid support in the kernel recently
(such as write-intent-bitmaps) which require a new version of mdadm.
(can be found at http://www.cse.unsw.edu.au/~neilb/source/mdadm/)

Is this a potential for FC5? What work needs to be done to get it integrated?
