Merge tag 'for-7.3-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave...

Pull btrfs fixes from David Sterba:

 - tree-checker updates, validate values in b-tree item keys, other item
   length checks

 - don't do unnecessary transaction commit fallback when logging parent
   directories

 - in zoned mode, initialize space info of a block group early enough so
   it does not lead to NULL pointer dereference
