From: Dave Chinner <dchinner@xxxxxxxxxx>
There are quite a few realtime device definitions shared with
userspace. Move them from xfs_rtalloc.h to xfs_rt_alloc_defs.h
so we don't need to share xfs_rtalloc.h with userspace anymore.
This removes the final __KERNEL__ region from the XFS kernel
codebase. Yay!
