Hi Kees,

After merging the kspp tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commit

1d48144b9688 ("xfs: Define usercopy region in xfs_inode slab cache")

interacting with commit

43518812d297 ("xfs: remove support for inlining data/extents into the inode fork")

from the tree.

I just reverted the kspp tree commit as it seems like it is no longer
needed.
