In 3.6.6 some of the patches of the series "Bunch of DIO/AIO fixes V4"
by Dmitry Monakhov have been applied but not all. In particular, patch
9, "fix ext4_ext_remove_space tree traversal" is not there. We're
getting hit by the null pointer dereference in our main file servers.

What's the situation of this patch? Any reason it's not applied?
