It looks like you diffed from a tree that has Josef's patch
called "Btrfs: add metadump_v2 support to the kernel" [1] applied,
which never made it upstream (probably got lost in the 4.0 mess).
This patch is not yet in 4.4rc, so merging your patch will introduce
half of Josef's patch but with the bits in inode.c missing.
It's based from integration-4.4.
This bit is copied from btrfs-progs.
And I added this is to make kernel accept such dump image as it used to.
(Along with fsid chaning image)
Not sure about the inode part.
But I added this just to keep the same behavior for such images.
cc:'ing Chris to make sure he applies that missing patch as well.
And if Josef's patch can be merged into kernel, that would be best.
Thanks,
Qu
cheers,
Holger
