FYI, I am testing the hp portion and hit and existing oops in
radix_tree_gang_lookup (fixed by upstream block layer patch):
http://www.gossamer-threads.com/lists/linux/kernel/880705?page=last
I saw the problem when doing this sequence:
1) multipath -F
2) "rmmod qla2xxx"
* This would trigger the oops
I added the following upstream commit
ffc4e7595734cf768fa60cea8a4d545dfef8231a on top of your patches and it
seems to have fixed the problem:
