Thanks, so with this we can proceed with merging, the question is how.
This is in generic fs/ code but not plain VFS and affecting only btrfs
and xfs. I suggest the following:

I'll take the patches to a branch separate from other btrfs patches, add
rev-by and stable tags and send an extra pull request to Linus.

Before that the branch can spend some time in btrfs' for-next among
other topic branches so there's linux-next exposure.

I don't mean to sidestep VFS maintainers, but previous remap changes
don't have Al Viro's signed-off either, so I hope that when at least
Darrick is fine with the proposed way then let's do it. If not, please
let me know.
