Yes - basically all of the xfs_* files in libxfs/ and include are
copies of the kernel code. Unfortunately it's not 1:1 at the moment
as there are a few differences:
- the userspace code uses a single <xfs.h> include instead of the
individual includes in kernel space
- some files aren't fully used in userspace and the userspace variants
miss some functions
- if I remember correctly some functions aren't static in the userland
version.
The latests xfsprogs release contains a major rebase of the code, but
if you have enough time to a resync with the code for the Linux 3.2
merge it would help a lot.
