There are few dependencies with this patchset.

These patches should go in before "Add support for augmented rbtrees":

"btrfs: use RB_ROOT to intialize rb_trees instead of settingrb_node to
NULL"
http://lkml.indiana.edu/hypermail/linux/kernel/1002.2/02946.html

"[patch 0/3] Fixup rb_root initializations to use RB_ROOT"
http://lkml.indiana.edu/hypermail/linux/kernel/1002.2/03037.html


And this is an x86 bug fix on top of "Migrate to rbtree only backend for
pat memtype management"
http://lkml.indiana.edu/hypermail/linux/kernel/1002.3/00346.html


Thanks,
