--- Comment #2 from Benjamin Kaduk <bjk at FreeBSD.org> ---
The XFS support was removed from stable/10 (then head) in r247631, as part of
the MPSAFE-VFS project.  The XFS kernel code was not safe to operate without
the VFS layer automatically grabbing the Giant kernel lock.  The compat code in
the VFS to automatically grab the Giant lock was removed to further general
improvements to the VFS layer, and will not be reintroduced.  Even read-only
support would require substantial work, and I do not expect that it will be
forthcoming.
