Subject: linux-next: build failure after merge of the xfs tree

Hi all,

After merging the xfs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commit

  d5e20bfa0b77 ("fs: add generic UNRESVSP and ZERO_RANGE ioctl handlers")

I have used the xfs tree from next-20191028 for today.
