Ok, so this is causing problems with merging other code into
userspace. What I'm trying to do is keepthe kernel fs/xfs/libxfs/
code as close to identical with the xfsprogs libxfs/ code so that
patches just port straight across. I came across this difference
because my rmap btree patches fail to apply cleanly to xfs_ialloc.c
and it's because of all this missing code in userspace.

Rather than wait another day or two for you to rework this, Brian,
I'm simply going to rework this series to pull all the kernel patches
across and make it compile in userspace so that I can pull all the
rmap btree stuff across without needing to rework bits and peices of
the patchset.
