FYI, there are patches to extend ext4 to store xattr's in a separate
inode.  They were submitted by the Whamcloud (formerly Oracle, Sun,
Clustrefs -- the Lustre folks).

Unfortunately I haven't had the personal time and review bandwidth to
go over the patches, and they haven't been rebased in a while.  I'm
not opposed to them; they just need some time and loving attention
from folks with ext4 expertise to accelerate the process of getting
the patches reviewed, and in mainline.
