Hi all,

I'm seeing a xfsprogs for-next branch (HEAD is f77f9908851e) build
failure in my test.

This build failure only happens if I installed 4.12-rc kernel headers,
which has /usr/include/linux/fsmap.h installed, so that in
xfsprogs/include/builddefs it has "HAVE_GETFSMAP = yes" defined.

e.g. install Fedora rawhide kernel package and its kernel header files,
and re-compile xfsprogs.
kernel-4.12.0-0.rc6.git3.1.fc27.x86_64
kernel-headers-4.12.0-0.rc6.git3.1.fc27.x86_64
