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?
