[PATCH 00/20] btrfs-progs: extent tree v2 global root support prep work

[Josef Bacik <josef@toxicpanda.com>]

Hello,

This is a series of patches to do all the prep work needed to support extent
tree v2.  These patches are independent of the actual extent tree v2 support,
some of them are fixes, some of them are purely to pave the way for the global
root support.  These patches are mostly around stopping direct access of
->extent_root/->csum_root/->free_space_root, putting these roots into a rb_tree,
and changing the code to look up the roots in the rb_tree instead of accessing
them directly.  There are a variety of fixes to help make this easier, mostly
removing access to these roots that are strictly necessary.  Thanks,

Josef
