The XFS stuff is non-trivial, causes on-disk format changes and
likely breaks xfsdump/xfsrestore, so the XFS patch is a no-go until
that is sorted out.
Given the short time until the merge window and that the XFS patch
needs to be significantly revised, it's already too late for the XFS
changes to be considered for the 3.8 merge window. Hence I'd
suggest that you are going to be targeting 3.9 for the XFS changes.

The XFS changes definitely need to be staged through the XFS tree
given the complexity of the changes, the amount of validation that
is required. Also, it is likely that there are significant conflicts
against changes already staged for 3.8, so getting it upstream
through the XFS tree is the only option that I'd consider
acceptible...
Cheers,
Dave.
