# fs/Makefile enters fs/xfs twice if CONFIG_XFS_FS is y, once for kernel and

# even if xfs is in kernel.  Alas the shorthand form

# fails when the makefile is run more than once, code gets compiled as both
# kernel and as module, which one gets linked depends on the phase of the moon.
# I just love these layer violations where a makefile behaves differently
# depending on changes to its parent.  Work around by only setting obj-m when
# xfs is selected as a module.  Keith Owens.
