Subject: Btrfs: pass the correct root to lookup_free_space_inode()
X-Git-Tag: v2.6.39-400.9.0~845^2~43

Btrfs: pass the correct root to lookup_free_space_inode()

Free space items are located in tree of tree roots, not in the extent
tree.  It didn't pop up because lookup_free_space_inode() grabs the
inode all the time instead of actually searching the tree.
